Technological Advancements from Dry Compasses to Liquid-Filled Variations
Tumblr media
The dry compass, also known as the magnetic compass, has been a crucial tool for navigation for centuries. However, with the advancement of technology, the dry compass has undergone significant improvements, leading to the development of liquid-filled variations. In this article, we will explore the evolution of the compass, from the traditional dry compass to the modern liquid-filled compass, and how these advancements have impacted navigation. onlinecompass.net
The Traditional Dry Compass
The dry compass, also known as the magnetic compass, has been used for navigation for thousands of years. It is a simple instrument that uses a magnetized needle to indicate direction. The needle is balanced on a pivotal point, allowing it to rotate freely when the compass is moved. The needle points towards the Earth's magnetic north pole, which is located near the geographic North Pole. The dry compass has a direction-of-travel arrow or a rotating bezel that indicates the direction of the desired course.
The dry compass is a reliable and straightforward tool for navigation, but it has some limitations. For instance, it can be affected by magnetic fields, such as those generated by nearby metal objects or electrical currents. This can cause the needle to deviate from its natural alignment, leading to inaccurate readings. Moreover, the dry compass is not very stable, and it can be affected by wind, vibrations, or other external factors that can cause the needle to oscillate or become stationary.
Tumblr media
The Liquid-Filled Compass
In the 19th century, the development of the liquid-filled compass revolutionized navigation. The liquid-filled compass is a significant improvement over the traditional dry compass, as it addresses many of the limitations of its predecessor. The liquid-filled compass is a sealed capsule filled with a liquid, usually a light oil or alcohol, that surrounds the magnetized needle. The liquid helps to dampen the oscillations of the needle, making it more stable and less affected by external factors.
The liquid-filled compass is also less susceptible to magnetic interference, as the liquid helps to shield the needle from external magnetic fields. This makes it a more reliable tool for navigation, especially in areas with high levels of magnetic interference, such as near power lines or industrial sites.
In addition to its improved stability and resistance to interference, the liquid-filled compass has another advantage: it can be made more accurate. The liquid-filled compass can be calibrated to account for the Earth's magnetic variation, which is the difference between magnetic north and true north. This allows navigators to adjust the compass to provide more accurate readings, making it easier to determine their direction and location.
The liquid-filled compass has become a standard tool for navigation, and it is widely used in various industries, such as aviation, maritime, and military operations. It is also used by outdoor enthusiasts, such as hikers, campers, and sailors, who need a reliable and accurate compass for navigation.
Conclusion
In conclusion, the compass has undergone significant advancements over the centuries, from the traditional dry compass to the modern liquid-filled compass. These advancements have improved the accuracy, stability, and reliability of the compass, making it a crucial tool for navigation. The liquid-filled compass has become a standard tool for various industries and outdoor enthusiasts, providing them with a reliable and accurate means of determining their direction and location. As technology continues to evolve, we can expect the compass to undergo further improvements, leading to even more accurate and reliable navigation tools.

A stick or straight twig
A clear patch of ground
A sunny day
Steps to Create
Plant the stick: Firmly stick the twig into the ground, making sure it stands upright.
Mark the shadow: Wait for approximately 15 minutes to allow the sun to move. Mark the tip of the shadow cast by the twig with a stone or another object.
Connect the points: Draw a line connecting the original position of the twig with the marked stone. This line represents the approximate east-west direction.
Determine north: Stand with the first mark (original position of the twig) on your left and the second mark (stone) on your right. You will be facing the approximate north direction.
3. Navigating without Water
In certain situations, you might find yourself without access to water, making the traditional water-based compass unusable. However, you can still navigate effectively using alternative techniques:
3.1. Shadow Tip Method
Utilizing the sun's position and the shadow tip method, you can determine the cardinal directions even without a water compass.
Materials Needed
A straight stick or a simple sundial (optional)
Sunny weather
Steps to Follow
Find a flat surface: Look for a clear and flat surface where the sun's shadow will be easily visible.
Position the stick or sundial: If you have a stick or a sundial, position it upright on the ground. Otherwise, you can simply use a straight twig stuck vertically into the ground.
Mark the tip of the shadow: As the sun moves, mark the tip of the shadow cast by the stick every 10 to 15 minutes.
Determine the cardinal directions: Draw a straight line through the marks from the first mark (earliest time) to the last mark (latest time). This line represents the approximate east-west direction. Perpendicular to this line, the north-south direction can be determined.
Tumblr media
3.2. Watch Method
Using an analog watch (with hour and minute hands), you can improvise a compass.
Materials Needed
An analog watch
A clear view of the sun
Steps to Follow
Hold the watch horizontally: Place the watch on a flat surface and hold it horizontally.
Point the hour hand at the sun: Aim the hour hand of the watch directly at the sun. Keep in mind that the time on the watch must be adjusted to match the local solar time.
Bisect the angle: Mentally draw an imaginary line that bisects the angle between the hour hand and the 12 o'clock mark on the watch. This imaginary line represents the north-south direction. The direction opposite to the north is south.

For example, the North Star (Polaris) appears almost stationary and approximately aligned with the Earth's axis, making it a reliable indicator of the north direction.
4.2. Nature's Signs
Nature provides subtle hints that can help you find your bearings. For instance, moss tends to grow on the north side of trees and rocks in many regions. Although not a foolproof method, it can offer a general sense of direction.
4.3. Tracking the Sun and Moon
During the day, the sun can be a reliable compass when you know its general path. The sun rises in the east and sets in the west, giving you an approximate east-west direction. Similarly, the moon can provide directional cues, especially when it is close to the horizon.
5. Finding Direction in a Pinch
In dire situations, you might not have access to any tools or materials for crafting a compass. In such cases, relying on your instincts and natural indicators becomes vital:
5.1. Using a Wristwatch
If you have an analog wristwatch, you can use it as a makeshift compass in a pinch.
Steps to Follow
Point the hour hand at the sun: Hold the watch horizontally and align the hour hand with the sun.
Find the bisecting line: Imagine a line bisecting the angle between the hour hand and the 12 o'clock mark. This line points roughly north-south.
5.2. Shadow Stick Method
Utilizing only a stick and the sun's position, you can find the approximate north-south direction.
Steps to Follow
Plant the stick: Stick the straight twig into the ground vertically.
Observe the shadow: Note the direction of the shadow cast by the twig.
Wait for 15 minutes: Let the sun move, and the shadow will change direction.
Draw the lines: Mark the initial position of the shadow and connect it to the current position. The line from the initial mark to the current mark represents the east-west direction, and perpendicular to that is the north-south direction.
Tumblr media
6. Alternative Techniques to Water for Homemade Compasses
While water-based compasses are easy to create, there are alternative methods to construct compasses without relying on water:
6.1. Magnetized Paper Clip
If you have a paper clip and a magnet, you can create a simple compass:
Materials Needed
A paper clip
A magnet
Steps to Assemble
Magnetize the paper clip: Stroke the paper clip with the magnet in one direction multiple times to magnetize it.
Place it on a flat surface: Lay the paper clip on a flat, level surface, allowing it to move freely.
Observe the orientation: After a few seconds, the paper clip will align itself with the Earth's magnetic field, with one end pointing north and the other south.
6.2. Leaf and Sun Compass
If you lack access to water and other materials, you can still create a basic compass using a leaf and the sun:
Materials Needed
A leaf (preferably broad and flat)
A clear view of the sun
Steps to Assemble
Find a flat surface: Look for a clear, flat surface with an unobstructed view of the sun.
Position the leaf: Place the leaf on the ground, ensuring it lies flat and stable.
Observe the orientation: The leaf will slowly align itself with the north-south direction as the sun moves across the sky.
7. Exploring Unconventional Methods
Sometimes, unconventional methods can serve as effective compasses when you're in a bind. While these methods may not be as accurate as traditional compasses, they can provide valuable directional insights:
7.1. Using an Insect Compass
Some insects, such as ants, exhibit remarkable navigational skills. They often follow specific patterns and can help indicate the direction you should take.
7.2. Observing Animal Behavior
In the wild, observing the behavior of animals can provide insights into the local landscape. For example, birds often fly in the direction of their nests or migration routes, while animals may drink from water sources that lie in a particular direction.
8. Non-Traditional Compass Techniques for Survival Situations
When you find yourself in a survival situation, creativity and adaptability become crucial. Here are some non-traditional compass techniques to aid in navigation:
8.1. Making Use of Shadows
In the absence of a magnetic compass, you can rely on shadows to determine cardinal directions. Use the shadow tip method as described earlier to find your way.

How Does a Needle Act as a Compass?
A compass is a valuable tool used for navigation, indicating the cardinal directions of north, south, east, and west. At its core, a compass works based on the principle of magnetism. The key component of a compass is a magnetic needle, which aligns itself with the Earth's magnetic field. Understanding how a needle acts as a compass is essential before delving into the process of converting a simple needle into a functional compass. onlinecompass.net
Magnetism and Earth's Magnetic Field:
To understand how a needle functions as a compass, we need to grasp the concept of magnetism. Magnets have two poles, the north pole, and the south pole. Opposite poles attract each other, while like poles repel. The Earth itself behaves like a giant magnet, with its magnetic north pole located near the geographic North Pole and the magnetic south pole near the geographic South Pole.
The magnetic needle in a compass is usually a thin piece of ferromagnetic material, often made of steel, which becomes magnetized when exposed to a magnetic field. The Earth's magnetic field exerts a force on the needle, causing it to align itself in a north-south direction.
Tumblr media
Gathering the Materials: What You'll Need to Make a Needle Compass
Before we start the conversion process, it's essential to gather the materials required to construct a simple needle compass. While the process is relatively straightforward, ensuring you have all the necessary components will make the task more efficient and enjoyable.
Needle: A thin steel needle is the primary component of the compass. It should be about an inch or two in length.
Cork or Small Float: This will serve as the base for the needle to float upon.
Small Bowl or Dish: To hold water for the float.
Magnet or Magnetic Object: To magnetize the needle.
Ruler and Marking Pen: For calibration and marking.
Map or GPS Device: To cross-reference your readings for navigation.
Step-by-Step Guide: Creating a Stable Base for Your Needle Compass
Prepare the Cork or Float: Take the cork or small float and ensure it fits comfortably in the chosen bowl or dish. If needed, trim the cork to the appropriate size.
Create a Centering Hole: Use a sharp object to create a small hole in the center of the cork or float. Make sure it is just wide enough to snugly hold the needle.
Place the Float in Water: Fill the bowl or dish with water and gently place the cork or float on the water's surface. Ensure it is stable and not tipping to one side.
Test the Needle Placement: Take the needle and carefully place it in the hole on the float. Allow the needle to float freely and observe if it aligns with the north-south direction.
Magnetizing the Needle: Techniques to Polarize the Needle's Magnetic Properties
Now that you have created a stable base for your needle compass, the next step is to magnetize the needle. Without magnetization, the needle will not align itself with the Earth's magnetic field, rendering it useless as a compass. There are several ways to magnetize the needle:
Using a Permanent Magnet: Take a permanent magnet and stroke the needle in one direction repeatedly. This process aligns the domains of the steel in the needle, making it temporarily magnetic.
Using Electromagnetic Induction: You can also magnetize the needle by using electromagnetic induction. Pass an electric current through a coil of wire and insert the needle inside the coil while the current flows. This process induces magnetism in the needle.
Rubbing with a Magnetic Material: Rub the needle against a strong magnet in one direction several times. This friction will impart magnetic properties to the needle.
Balancing the Needle: Ensuring Equilibrium for Accurate Compass Readings
Once the needle is magnetized, it should settle into an equilibrium position where it aligns itself with the Earth's magnetic field. However, achieving perfect equilibrium may require some additional adjustments:
Counterbalance: If one end of the needle is heavier, it may cause the needle to tilt. Attach a small weight, such as a tiny piece of clay, to the lighter end of the needle to balance it out.
Check for Interference: Ensure that there are no magnetic or metallic objects nearby that could interfere with the needle's alignment.
Orienting the Compass: Establishing North-South Alignment
With a magnetized and balanced needle, your compass is now ready for use. However, before you can navigate with it, you need to orient it to the true north-south direction:
Finding True North: Use a map, a GPS device, or known landmarks to determine the direction of true north.
Aligning the Compass: Rotate the compass until the needle aligns with the true north direction. The "N" on the compass should point toward the geographic North Pole.
Calibrating for Deviation: Accounting for Local Magnetic Anomalies
While your homemade needle compass can now point you in the general direction of north, it may not be perfectly accurate due to local magnetic anomalies. Deviation refers to the difference between true north and magnetic north, and it varies depending on your location.
To calibrate for deviation:
Obtain Deviation Information: Consult nautical charts or online resources to find the deviation value for your area.
Apply Deviation Correction: Once you know the deviation for your location, add or subtract the value from your compass reading to get the correct direction.
Using Landmarks: Navigating with Your Homemade Needle Compass
With your needle compass calibrated and oriented, you are ready to navigate using basic landmark-based techniques:
Taking Bearings: Pick a distant landmark that you can identify on the map and align your compass with it. The direction the compass points to is the bearing.
Using Bearings for Orientation: As you move, continuously take new bearings to landmarks to stay on track and confirm your position on the map.
Enhancing Compass Accuracy: Tips for Improved Performance and Precision
While a homemade needle compass can be a valuable tool, there are ways to enhance its accuracy and performance:
Regular Magnetization Check: Over time, the needle may lose some of its magnetism. Periodically check and remagnetize the needle to maintain its accuracy.
Store Away from Magnetic Interference: Keep your compass away from magnetic or metallic objects when not in use to avoid interference.
Use with a Map or GPS: While a compass is useful, it works best when used in conjunction with a map or GPS for cross-referencing and added accuracy.
Exploring Alternative DIY Compass Designs: Beyond the Basic Needle Compass
Apart from the traditional needle compass, there are various alternative DIY compass designs you can explore:
Floating Leaf Compass: Instead of a needle, use a small leaf or piece of straw floating in water as the indicator.
Sun Compass: Create a sundial-like compass using a stick and the direction of the sun's shadow.
Dry Compass: Replace the water with a pivot point and use a dry needle balanced on the pivot as the indicator.
Conclusion
Converting a simple needle into a functional compass is a fascinating process that allows you to harness the power of magnetism for navigation. By understanding the principles of magnetism and the Earth's magnetic field, gathering the necessary materials, magnetizing the needle, and calibrating for deviations, you can create your own reliable and accurate homemade needle compass. With proper orientation and the use of landmarks, your DIY compass becomes a valuable tool for exploring the world around you. Don't stop at the basic needle compass; feel free to experiment with alternative designs to enhance your compass-making skills and further your navigational abilities.

What does N mean in the compass?
A compass is a simple yet essential navigational tool that has been used for centuries to determine direction. Consisting of a magnetic needle suspended on an axis, the compass points towards the Earth's magnetic field, specifically towards the North Magnetic Pole. The four cardinal directions - north, south, east and west - are the main points of reference on the compass. In this article, we will examine the importance of the letter "N" in the compass and its important role in navigation. onlinecompass.net
Understanding the importance of N in the compass
The letter "N" stands for North, one of the main directions in the compass. North is considered the most important point of reference because it provides a fixed framework of orientation. When using a compass, aligning the needle with the north pointer allows you to accurately determine your course and navigate with confidence. Understanding the significance of "N" is the key to mastering the use of a compass.
Tumblr media
North as reference point
In the context of a compass, north serves as a reference point against which all other directions are determined. Knowing where north is, you can easily determine south, east and west. North represents the direction toward the North Pole, where the Earth's magnetic field lines converge. This magnetic north is distinct from true north, which is directed towards the geographic north pole. While the two are similar, there are some differences between them that we'll explore below.
Use N to determine direction
To navigate with a compass, it is necessary to align the needle with the north pointer. Once aligned, you can read the other cardinal directions on the compass rose and determine your course accurately. For example, if you want to travel east, you have to turn and go in the direction where the east pointer lines up with the needle. Using the N pointer as a starting point, you can easily determine any desired direction and move towards it.
Magnetic North vs. True North: Exploring the Differences
While north on a compass generally refers to magnetic north, it is important to understand the distinction between magnetic north and true north. Magnetic North is the direction towards the North Magnetic Pole, where the Earth's magnetic field lines are located. However, true north is a direction toward the geographic North Pole, the northernmost point on Earth's surface. The difference between these two directions is known as magnetic declination and varies based on your location.
The role of N in the orientation of maps and navigation tools
The N in a compass not only helps you determine direction in the field, but also plays a vital role in orienting maps and other navigational tools. By aligning the north needle of the compass with the north-south grid lines on the map, you can ensure that the map has the correct orientation of the Earth's magnetic field. This orientation is important for accurately locating landmarks, planning routes, and coordinating with other navigation aids.
N as a symbol for northern hemisphere orientation
In addition to its practical significance, the letter "N" has become a symbol for the northern hemisphere orientation in various navigational instruments and maps. It represents the hemisphere that lies north of the equator and is associated with a specific set of geographical and climatic features. Compasses and other navigation tools visually indicate the northern hemisphere as the starting point for orientation and exploration by highlighting the letter "N".
Historical significance of N in the design and use of the compass
Throughout history, the compass has played a vital role in navigation and exploration. The inclusion of the letter "N" in the compass dates back centuries and has remained a constant feature in compass design. From ancient Chinese compasses to medieval European seafarers' compasses, the letter "N" has served as a universal symbol for north, ensuring the continued understanding and use of the compass across cultures and time periods.
accounting for magnetic declination
One of the challenges that compass users face is calculating the magnetic declination. Magnetic declination refers to the angular difference between magnetic north and true north at a particular location. This variance is caused by changes in the Earth's magnetic field and the geographic distance from the North Magnetic Pole. Adjusting the magnetic declination when using a compass is very important for accurate navigation, as failure to do so can result in significant heading errors.
Conclusion: acceptance of N as a basic element in compass orientation
As a result, the letter "N" has significant importance in compass orientation. As a symbol of the north, as a vital reference point for establishing direction and orientation in relation to

What are some common mistakes when using a compass?
Using a compass: Common Mistake #1 – Not Understanding Magnetic Declination One of the biggest mistakes people make when using a compass is not understanding magnetic declination. Magnetic declination is the angle between true north and magnetic north at a specific location. This angle can vary depending on where in the world you are. If you don’t account for magnetic declination, your compass readings will be off, and you could end up heading in the wrong direction. To avoid this mistake, always check the magnetic declination for your location and adjust your compass accordingly.
Using a compass: Common Mistake #2 – Holding it Incorrectly Another common mistake is holding the compass incorrectly. Many people hold the compass too close to their body, which can cause interference with the magnetic needle. When using a compass, hold it away from your body at arm’s length, and make sure it’s flat and level. This will ensure the magnetic needle can move freely and give you accurate readings.
Using a compass: Common Mistake #3 – Not Accounting for Local Attraction Local attraction is another area where people commonly make mistakes. Local attraction is any interference that can affect the accuracy of your compass readings. This can come from metal objects or other magnetic fields in the immediate area. To avoid this mistake, move away from any metal objects or sources of interference when you take your compass readings.
Using a compass: Common Mistake #4 – Not Using a Map Using a compass without a map is another mistake that people often make. A compass is only useful if you know where you are and where you need to go. Bringing a map with you can help you navigate more accurately and avoid getting lost. When using a compass, always use it in conjunction with a map so you can get a clear sense of direction and location.
Using a compass: Common Mistake #5 – Not Practicing Enough The last mistake people make when using a compass is not practicing enough. Compass navigation takes practice, and if you don’t use it regularly, you’re more likely to make mistakes. Make sure you know how to use your compass before you head out on a trip, and practice using it in different environments and conditions. The more you practice, the more confident you’ll be using a compass and the fewer mistakes you’ll make.

What is Compass Real Estate?
Compass Real Estate was founded in 2012 as Urban Compass. Founders Robert Reffkin and Ori Allon set out to disrupt the property industry starting with New York City and expanding to more than 300 offices across the country. Compass is a Fortune 500 company and the largest residential real estate brokerage in the United States.
Tumblr media
Compass does more than just support agents. It provides an integrated suite of cloud-based software to the Realtors who work with this brokerage. From the initial meeting to the final closing appointment, agents have tools at their fingertips to streamline the buying or selling experience.
This company focuses on volume. By maximizing the number of Realtors it works with, Compass can increase its annual sales while still only charging small fees to its agents. Realtors might find that working with Compass is an ideal brokerage option because they can take home a higher percentage of their commissions while still getting support through the software tools.
In 2022, Compass reported $6 billion in transactions with more than 211,500 total homes bought and sold by customers. It has more than 13,000 active principal agents – a 2,000-agent increase since 2021. Compass continues to report high levels of agent retention even as other brokerages notice a decrease in the total number of agents on staff.
Once you have a full understanding of how Compass Real Estate works, you can decide if hiring one of its agents is right for you. A tech-forward Realtor might be a good fit for your home sale.
How does Compass Real Estate make money? Compass Real Estate is a brokerage. When you close on your house (buying or selling) with a Compass agent, you pay the Realtor a fee. In turn, the Realtor pays a percentage of the commission to the brokerage.
When Compass Real Estate first launched, it was built with the idea that Realtors would receive salaries and bonuses rather than traditional commissions. This was meant to make the brokerage more competitive in recruiting agents while increasing profitability. After all, if the market took a turn, a Realtor could still count on their monthly salary.
However, agents enjoy working on commission. Compass changed its original business model back to the commission-based system within a few years of launching. Today, Compass says that it supports one of the largest groups of small business owners and entrepreneurs: residential real estate agents through its services.
The change to the pay structure was well received by agents. In 2019, Compass had more than 140,000 applicants to join its brokerage and only hired the top 1%. Commission rates are negotiated on an individual basis and are included in agent contracts. More experienced agents, Realtors with large client funnels, and professionals who work with luxury properties will likely pay lower fees to the brokerage because they will still bring in more money to the company over the course of the year.
In exchange for these fees, Compass agents have access to the company’s proprietary software systems. This makes completing real estate transactions faster and easier. If an agent can use technology to free up a few hours each week, they will have more bandwidth to take on more clients. This increases both the annual income of the agent and the revenue of the brokerage.
What does the Compass proprietary technology do? The two biggest assets of this brokerage are its agents and its software. Changing how Realtors are paid allowed Compass to keep its agents engaged and happy. Similarly, the company works to constantly maintain and improve its suite of digital tools that improve the real estate process.
Compass has a strong engineering team and continues to hire employees to develop apps and software. One area where Compass differentiates itself is in machine learning and artificial intelligence (AI). This has helped agents improve their decision-making, including setting more effective pricing for homes and choosing the best time for a sale. The software suite can even help agents decide on which potential clients to target and when.
Compass has built its brand around the technology it develops; however, it’s not the only company to do this. Many brokerages have internal systems and tools to help agents. Other brands are known for their digital systems and customer-facing tools.
In fact, in 2019, Zillow filed a lawsuit against Compass claiming the brokerage hired former Zillow employees who had signed non-compete clauses. Zillow claimed Compass used the employees to steal trade secrets and learn about the technology tools it was building. The two companies reached a private settlement through mediation.
In most cases, home buyers and sellers won’t need to interact much with the Compass digital tools. While there are some client-facing apps, homeowners and buyers will mostly benefit from a streamlined real estate experience while their agent uses this technology on the back end.

The compass is not working on my Android phone
We often get queries from Android users who have tried opening a compass app on their phone and it just freezes, or says “can not access magnetic field data.” This is a common problem. Below are some tips on why this could be happening and how you might be able to get the compass to work.
Does your device have a magnetometer sensor?
A lot of compass apps including Accurate Compass work by using data from the magnetometer sensor in your Android device. Not all devices have this sensor, so the first thing to check is whether your device has – if not you may be out of luck!
The website gsmarena has useful info for many different makes of phone. Check the “Sensors” section under “Features”. If it doesn’t mention a magnetometer or compass sensor you probably don’t have one.
If your device doesn’t have a magnetometer, you still might be able to use a compass app which works via GPS – check for this in the app description.
Tumblr media
Check you are away from any magnetic interference
The compass sensors are very sensitive to interference. Make sure you are holding your device away from any electric cables/magnetic objects. Also check you don’t have a magnet on your case as this can interfere with the sensors.
Try calibrating your device
Over time your sensors can stop working accurately. Try re-calibrating your device using the following method:
Wave your device in a figure of 8 pattern rotating it in different directions as you do this. If your device is very hot you may need to wait for it to cool down. You can also try switching it off and on again. Be patient as this can take a few minutes to work.
Compass Calibrationv
If you are unsure of the accuracy of your sensors, you can check this within the “sensor status” menu option of our Accurate Compass app. This will show an information screen setting out the accuracy of your magnetometer and accelerometer and whether any calibration is required.

How Compasses Changed the World
How Compasses Changed the World The compass was invented more than 2000 years ago. But it took more than 1000 years before it was used for finding directions and navigation. But a compass is a device that shows people where magnetic north is! So why was it invented if not for navigation? How was it first used?
Marvellous Magnets An early form of the compass was created by Chinese inventors around 250 BCE. They used the device to help them align buildings and furniture according to the environment and forces of nature. This technique is called feng shui (you say it like this: foong schway) and is still used today.
These early compasses were built using lodestone, which is a mineral that lines up with Earth’s magnetic field. Some experts believe the ancient Olmec people of Mexico might have used lodestones in a similar way to the Chinese, but 750 years earlier.
Eventually, someone realized that the lodestones were better at showing real directions, and that led to them being used as compasses. The pointing needle was a spoon-shaped piece of lodestone, set on a stone slab marked with some constellations and the points of the compass (north, south, east, west, and points between them). The handle of the spoon always pointed south.
The Compass Takes Off More than 1200 years ago, people figured out how to magnetize iron needles and these replaced the lodestone. These newer compasses were more accurate and portable, and could finally begin to be used by travellers and explorers.
Before they had compasses, people navigated by the position of the Sun during the day and the movement of the stars at night. Obviously, this did not work very well in stormy weather or when clouds filled the sky. Sailors had to keep the shore in sight so they could see landmarks, or they risked getting lost.
Compasses made it possible for explorers to sail far out into oceans and away from land—no matter what the weather was like. This led to more exploration, the discovery of new countries, and trade with other cultures. Compasses also helped ships stay on course, which was important for explorers who were trying to return home.
Compasses in Modern Times The world-famous scientist Albert Einstein often spoke about how he had been fascinated by compasses when he was a little boy. The movement of the needle amazed him, and he and other scientists investigated magnetism, which has led to many scientific discoveries.
Although many people still use compasses, in the late 1900s, people began using the Global Positioning System (GPS) to get around. It uses position and time information from satellites circling Earth to provide directions.
Fun Facts
The four main points marked on a compass—north, south, east, west—are called cardinal points.
A modern hand-held compass uses a magnetized needle inside a small container filled with fluid. The fluid is often oil, kerosene, or alcohol. The fluid helps the needle remain steady.
During World War II, British pilots carried secret tools that they could use to escape if they were captured. The tools were hidden in everyday objects. Small compasses were hidden in boots, pens, and even buttons!

How do pilots use magnets?
Since the beginning of flight, pilots have been using the magnetic compass for navigation. It doesn't matter if you're flying a Piper Cub or a Boeing 747, you'll find a magnetic compass in the cockpits of almost any aircraft. That is, unless you're flying the latest, most technologically advanced glass cockpits, which we'll cover in a separate article.
So here's what you need to know about an instrument that's been in aircraft cockpits for over 110 years, and the errors associated with it. onlinecompass.net
How They're Made Magnets in a compass make it align with the magnetic North Pole. In airplanes, your compass is almost always set on top of the dash or hung from the top of the windshield frame, in order to keep it as far away from electrical gear as possible to reduce magnetic deviation (more on this later).
Back in the days before kerosene filled the inside of a magnetic compass, alcohol was used as the primary lubricant and non-freezing liquid… Hence the nickname a "whiskey compass." Rumor has it that some pilots broke into their whiskey compasses on long layovers…but that's another story.
Magnetic Deviation Instruments in your airplane cause interference that affects your compass, and that interference is called deviation. Inside the compass, there are compensating magnets to counteract these fields of interference. A compass card is normally attached, showing what error correction to add for different headings, although the changes are normally just a few degrees.
Next time you're in the cockpit, try putting your headset on the dash near the compass and see if it changes the compass heading. The magnets in your headset speakers will almost certainly change the magnetic field enough to show a difference in heading.
Magnetic Variation Variation is the difference between true north and magnetic north. Isogonic lines are drawn on your sectional charts to show different lines of magnetic variation to help with planning your magnetic heading.
To find your magnetic course (in no wind, the heading you see on your compass), you'll either subtract easterly variation or add westerly variation. A great memory tool for this is "East is least, West is best." In this example, the variation is 14 degrees East, so you'd subtract 14 degrees from your true course to get your magnetic course.
Magnetic Dip Magnetic dip creates the most substantial errors in a compass. As you get closer to the North or South Pole, magnetic flux lines point downwards towards the poles, and your compass magnets dip towards the low side of a turn. When magnetic dip is pronounced, it's difficult to get actual readings. This error isn't much of a problem near the equator, where your compass points more or less horizontally and magnetic dip isn't a concern.
Acceleration And Deceleration Error Another major problem with magnetic compasses in airplanes is acceleration error. In the Northern Hemisphere, as you accelerate, your compass will show a turn to the North. And as you decelerate, your compass will show a turn to the South. When the speed stabilizes, the compass returns to normal. This error is greatest on East or West headings.
So how are you supposed to remember this? Use the acronym ANDS: "Accelerate-North, Decelerate-South."
Turning Errors During a turn from a Northerly heading, the compass briefly indicates a turn in the opposite direction. As for aircraft turning from a Southerly heading, the compass indicates a turn in the correct direction, but at a faster rate than is actually being turned.
How do you remember this one? Use the acronym NOSE: "North-Opposite, South-Exaggerated." Not too bad, right? The magnetic compass is tried and true. If everything else fails in your cockpit, you always have your magnetic compass. And now you know how it works, as well as the problems it has, too.

HOW TO KEEP YOUR COMPASS WORKING PROPERLY
A compass needle is a finicky thing. It has to be able to swing freely in a full circle, spinning in a near frictionless environment free of obstructions. The thin strip of metal has to be sensitive to be able to align itself with the Earth's magnetic fields, but its sensitivity also means that it can be thrown off either temporarily or practically permanently by what's around it. onlinecompass.net
Because precision is important (even a minor inaccurate reading at the start of your trip can translate to missing your goal by a great distance later on), you should take every precaution to ensure that your compass continues to function as best as possible. This means being aware of your surroundings when in the field and paying attention to how you store it when it's not in use.
Keep the following in mind to be sure you stay on course:
Metal that has a lot of iron in it known as ferrous metal can impact a compass. A large object such as a car or tower can draw the magnetized needle, making a precise reading difficult to secure. Even soil with a lot of iron in it can tweak your results. To minimize such distortion, be sure to use your compass a fair distance away from any known source of ferrous metal to ensure the most accurate bearings.
Similarly, electrical fields can make a getting a true compass reading difficult. Once again, cars can be the main culprits here. Basically, get away from your vehicle once you're ready to start some actual orienteering. Large objects such as power lines can interfere with an accurate reading, and smaller sources such as handheld electric devices can also prove to be a problem if they're in close proximity to the compass. Basically, keep your compass away from the sort of stuff you're heading into the wilderness to escape yourself.
Just as metal and electricity can temporarily befuddle a compass in the wild, the same factors can more seriously damage a compass if it sits next to them long-term. The longer you leave your compass on top of something ferrous, magnetic, or electrical, the greater the chance of the needle getting demagnetized which means it won't point the way toward magnetic north.
This should go without saying, but take care of your compass. Take care to not stack anything on it, drop it, or smash it. You may not be able to help it getting smacked if you slip on a trail and sit down hard on a rock with the compass in your pocket, but you can take care to store it somewhere that it will be relatively safe. A hard enough shock could cause a leak in the capsule holding the needle, which lets fluid out and air in. The reduced fluid and presence of increasingly larger bubbles will certainly interfere with the needle's ability to spin freely and provide an accurate reading. (Note that a small bubble, with a diameter of less than a quarter of an inch, may appear from time to time in the capsule. This can be attributed to changes in temperature and atmospheric pressure and shouldn't pose any sort of distortion problems.
Also, keep your compass away from direct heat sources. Don't leave it on the toaster at home or right on a rock in your campfire ring while out on a hike. The heat can melt the baseplate or capsule or, at the very least, distort some of the delicate equipment and lead to incorrect readings. Heat can expand the liquid in the capsule and damage the compass. With proper care and storage, your compass will last you for a lifetime of adventures.

When you get to 90 degrees north you will be standing on ice 6-10 feet thick, at the point at which all lines of longitude converge, above an ocean 13,000 feet deep There are only around 5 trips per year for 640 passengers A total of just 1,000 people a year reach this point You can get there on a nuclear powered ice-breaker The Pole is around 700 miles from the nearest land While there is not much wildlife at the Pole itself you are likely to see polar bears, seals, walrus, whales and plenty of birds along the way onlinecompass.net How to get to the North Pole
Though inaccessible for most of the year, it is possible to travel to the North Pole in June and July when the ice is thinner, or in April if travelling via helicopter. All North Pole voyages start and end in Helsinki, Finland, from where you'll fly by charter plane to Murmansk, in Northwest Russia to board your ship.
Travelling via icebreaker ship from Murmansk is the favourite route for most visitors. Crush through multi-year ice to reach 90 degrees north where you can disembark, stand atop 13,000 ft of Arctic ocean and gaze at a mosaic of ice sheets.

Do ships use compass?
The ship’s magnetic compass has been around in various forms for more than a millennium. Navigators all over the world discovered the properties of magnetic compasses. Since their development, ships carry compasses to help navigate when conditions required a reference aboard the ship to provide orientation. At night, or otherwise out of sight of familiar landmarks, a compass provides vital information for the navigator. onlinecompass.net
The compass on ships is often mounted in a binnacle which is a stand or housing. Its delightful name Binnacle derives from Latin habitaculum meaning “little dwelling place”.
This “little house” helps to protect the delicate compass from the elements. They usually contain a gimbal arrangement to hold the compass card horizontal despite the motion of the ship. In addition the binnacle usually contains a light of some sort to illuminate the compass face to facilitate reading it in the dark and shades to make reading it in sunlight easier. Binnacles are typically made of wood or brass or other non-ferrous metals. They are located in a place on the ship to allow the ship’s navigator to determine position and course. They may be located near the helm so that the sailor steering the ship can maintain the correct course.
But why would the compass need adjustment, it is always supposed to point North, right? The reason is that as a critical piece of navigational equipment the accuracy of a ship’s compass can literally mean the difference between life and death for a ship and her crew. The compass’ accuracy must be maintained at the highest possible precision while at sea.
The compass contains a magnet (or magnets) that orient predictably to the magnetic field of the earth.  In an ideal situation the compass would respond only to the earth’s magnetic field and would indeed always point to the Magnetic North Pole. In reality however, the compass magnet responds to the local magnetic field around it. That local field is a combination of the earth’s field modified by nearby magnetic influences.   Anything containing iron— everything from ballast stones with high iron content to ferrous (iron containing) metals such as nails and other fasteners, rigging, electrical equipment, engines and other machinery and of course iron and steel hulls— distort the local magnetic field around a compass. Ships with hulls made of iron or steel have very significant local distortion but even wooden (or fiberglass) vessels contain sufficient ferrous metals to influence the local magnetic field around the compass.
You will notice that on Wavertree the binnacle is located on a platform up over the deck and away from other structures.  This is in an attempt to minimize the effects of the magnetic properties of the iron ship and to place the compass close to the magnetic center of the ship.
