FE-2100AM magnetic declination measurement angle description

FE-2100AM magnetic declination measurement angle description

The magnet is placed on the sample table, the magnetic flux component is tested by the CZLA method, and the magnetic moment and the magnetic field deviation angle value of the main axis direction are obtained by calculation. The total magnetic moment M, the main shaft declination α, Øx, Øy, Øz, and the coil constant of the corresponding test coil can be displayed. The FE-2100AM(V3.0) magnetic material measurement system adds 5 angle displays:

Applicable scope and configuration of magnetic moment tester

Applicable scope and configuration of magnetic moment tester

In the quality requirements of rare earth permanent magnet materials, the accuracy and repeatability of magnetic moment test are far better than that of BH test instrument test standard sample transmission data, which can realize the full inspection of all magnetized samples, find the defects of the device in time, and ensure the judgment of the magnetic energy product grade of the material. The magnetic moment tester can automatically calculate the total magnetic moment M of the sample, which is particularly convenient to use.
