Product Description

 

TY3300 Magnetic Declination Tester

**The picture above is for reference, the actual delivery may be slightly different

1. Summary

TY3300 is a system dedicated to measuring the magnetic declination of permanent magnet materials. It is composed of three-dimensional Helmholtz coils, three-channel electronic flux meters, and computer software.  It is suitable for measuring the three magnetic flux components,Φ_X,Φ_Y,Φ_Z, on the XYZ axes of permanent magnet materials such as permanent magnet ferrite, AlNiCo, NdFeB, and Samarium Cobalt (SmCo) Magnets.  It automatically calculates the magnetic moments MX, MY, MZ, the total magnetic moment M, and the magnetic declination α for each axis.
It provides a good test for analyzing and evaluating the magnetization performance of permanent magnets.
 Reference Standard IEC 60404-14:2002 "Methods of measurement of the magnetic dipole moment of a ferromagnetic material specimen by the withdrawal or rotation method".

5. Magnetic Declination Measuring Principle

1. The vector relationship of M,M_X,M_Y,M_Z and the magnetic declination are shown in the above figure, and the measurement principle can be known:
2. Place the sample at the center of the Helmholtz coil platform to ensure that the magnetization direction of the sample is perpendicular to a certain axis.
3. With the sample removed from the coil and away from it, the magnetic flux components on the three-axis coil are measured: Φ_X,Φ_Y,Φ_Z.
4. The magnetic moments in the XYZ direction can be calculated according to the constants of the coils of each axis: M_X,M_Y,M_Z.
