DX-2012AM Permanent Magnet Angle Gauge
Currently, in most magnetic material production processes, there is no strict requirement for the accuracy and consistency of the material's magnetization direction. However, as the application fields of magnetic materials expand, the precision requirements for permanent magnets are increasing. Compared to the requirements of traditional magnetic materials, new application technologies have more specific requirements for the magnetic properties of permanent magnets. Since the magnetization vector direction (magnetic declination) of permanent magnets has a significant impact on the performance of precision magnetic components, the magnetic declination of permanent magnets is an important indicator for evaluating permanent magnet performance. The DX-2012AM permanent magnet magnetic declination meter provides an effective measurement solution for enterprises to produce high-end magnetic materials. The DX-2012AM permanent magnet magnetic declination meter consists of a three-dimensional Helmholtz coil connected to an independent three-component fluxmeter, forming the hardware testing part. By converting the test data of the three components through a microcomputer, a complete permanent magnet material quality testing system is formed. Place the magnet on the sample platform, test the flux components using the pull-up method, and calculate the magnetic moment and the magnetic field deviation angle value of the principal axis. It can display the total magnetic moment M, the principal axis magnetic declination α, Øx, Øy, Øz, and the corresponding coil constants of the test coils.

Measurement Principle
We know that a single Helmholz coil can be used to measure the magnetic moment M produced by a permanent magnet's magnetic moment along the magnetization axis. The magnetic moment M can be obtained through the relationship: M = k × Φ, where k is the Helmholz coil constant and Φ is the magnetic flux induced by the magnet on the coil. For the quality inspection of permanent magnet material samples after magnetization, the use of Helmholz coils for the transfer of quantity and quality between buyers and sellers has become very popular and widespread. It is particularly important to design single and three-dimensional Helmholz coils for the mutual transfer of parameters among international peers.
Anisotropic magnets always have their magnetic moment directions aligned with the anisotropic direction, but there may be cases where the anisotropic direction does not align with the magnet's axis direction. To show the projection of the magnetic block's anisotropic direction onto the block's own axis, a three-axis Helmholtz coil capable of displaying orthogonal fluxes Øx, Øy, Øz is required, which can then be used to calculate the orthogonal components of the magnetic moment, Mx, My, Mz.
The magnetic moment M is a vector, which can be divided into three components along three directions, specifically: aligned with the X, Y, and Z axes. The projection relationships are: cosαx = Mx/M, cosαy = My/M, and cosαz = Mz/M.
By measuring the magnetic flux Φx, Φy, Φz on the three-axis coil, and calculating the magnetic moments Mx, My, Mz in each direction based on the corresponding constants of each coil. The total magnetic moment M of the permanent magnet material can also be obtained by squaring each component of the magnetic moment and taking the square root.
