Description
technical field [0001] The invention relates to the field of anisotropic permanent magnet measurement, in particular to a permanent magnet magnetic declination measurement device and method. Background technique [0002] During the magnetic field orientation forming process of anisotropic permanent magnet materials, the orientation direction of the product is not parallel to the direction of the orientation magnetic field, resulting in a magnetic declination; A magnetic declination is generated between the axes. The existence of the declination angle of the permanent magnet causes the magnetic field to be generated in the non-magnetized direction of the magnet, forming a stray magnetic field. At present, there are limitations in domestic patents on magnetic declination measurement. CN101382586A invention patent is about the measuring device and method for the orientation degree of circular axially magnetized permanent magnets, and CN101833074A is also about the declination ...
