FE-2100AM permanent magnet magnetic declination measuring instrument
At present, in most of the magnetic material production processes, the accuracy and consistency of the magnetizing direction of the material are not strictly required. However, as the application field of magnetic materials becomes wider and wider, the accuracy of permanent magnets is getting higher and higher. Compared with the requirements of traditional magnetic materials, the new application technology has more special requirements for the magnetic performance of permanent magnets. Because the final magnetization vector direction (magnetic declination) of permanent magnets has an extremely important impact on the performance of precision magnetic components, permanent magnets The magnetic declination angle of a magnet is an important indicator to measure the performance of permanent magnets. The FE-2100AM permanent magnet magnetic declination measuring instrument provides a set of effective measurement solutions for enterprises to solve the production of high-end magnetic materials.
The FE-2100AM permanent magnet magnetic declination measuring instrument is composed of a three-dimensional Helmholtz coil connected to an independent three-component fluxmeter, which constitutes the hardware test part. The three-component test data is converted by a computer to form a complete set of permanent magnets. Material quality testing system. Put the magnet on the sample table, test the magnetic flux component by the pulling method, and obtain the magnetic moment and the deviation angle of the magnetic field in the direction of the main axis by calculation. It can display the total magnetic moment M, spindle magnetic declination α, Øx, Øy, Øz, and the coil constant of the corresponding test coil.

We know that a single Helmholtz coil can be used to measure the magnetic moment M produced by the magnetic moment of the permanent magnet on the axis of the magnetization direction. The magnetic moment M can be obtained by the relation: M=k×Φ, where: k is the Helmholtz coil constant, Φ is the magnetic flux induced by the magnet to the coil. For the quality inspection of the magnetized permanent magnet material samples, the use of Helmholtz coils for the transfer of quantity and quality between buyers and sellers has become very popular and universal. Single-dimensional and three-dimensional Helmholtz coils are designed to participate. The mutual transfer of parameters between international peers is particularly important.
The direction of the magnetic moment of the anisotropic magnet is always along the direction of the anisotropy, but it may happen that the direction of the anisotropy is inconsistent with the direction of the magnet axis. When it is necessary to display the projection of the magnetic block's anisotropy direction in the direction of the magnetic block's own axis, it is necessary to display the orthogonal magnetic flux Øx, Øy, Øz three-axis Helmholtz coils at the same time, and can be converted Get the orthogonal component magnetic moments Mx, My, Mz.
The magnetic moment M is a vector, which can be divided into three parts in three directions: X, Y, and Z are consistent in the three directions. The projection relations are: cosαx= Mx/M, cosαy = My/M and cosαz= Mz/M.
By measuring the magnetic flux on the three-axis coil: Φx, Φy, Φz, according to the constant corresponding to each coil, calculate the magnetic moment in three directions: Mx, My, Mz. The total magnetic moment M of the permanent magnet material can also be obtained by calculating the square and square root of the magnetic moment of each component.
