Can the ring magnet be magnetized in the inner ring ?

The ring magnet can be magnetized by the inner ring. For example, the inner ring is an S-pole and the outer ring is an N-pole full radial magnet, also known as a radiation ring. Most of them are made of NdFeB, which is mainly used in high-performance permanent magnet motors and sensors.... ...More>>
