Magnetic Declination Testing System

Introduction

A single Helmholtz coil can be used to measure the magnetic moment M produced by the permanent magnet in the magnetization direction. The magnetic moment M can be obtained through the relational expression M=KH×Φ, in which KH is the Helmholtz coil constant, while the Φ is the magnetic flux of the magnet induction to the coil. As for the quality inspection for the permanent material samples after being magnetized, Helmholtz coil is adopted and it is getting quite popular and universal. It is extremely important for the designed one-dimensional and three-dimensional Helmholtz Coil to participate in the mutual parameter transmission with its international peers.

Through the efforts of the company's collective wisdom, DX-2100AM magnetic declination measuring device was completed and can be put on the market as a new product. Compared with the original prototype, this enquipment imporves is the design of the machine body, add a pneumatic push sample structure for the separation of large rare earth permanent magnet sample, and coil constants K of XY axis coils are designed to be under 0.015cm. All of these meet the needs of customers at home and abroad. As the equipment does not involve the use of graphic record, we change the computer configuration to laptops, mainly used as the record of the test samples, and all the recorded parameters can be directly printed out.
