Method of magnetizing rare-earth magnet and rare-earth magnet |
摘要 |
The method of the present invention includes a step of preparing a rare earth magnet 22 disposed for forming a cylinder 22a, a first magnetizing step of applying a first external magnetic field H1 to the rare earth magnet 22, thereby forming a first region R1 magnetized from an inner side to an outer side of the cylinder 22a and a second region R2 magnetized from the outer side to the inner side, and a second magnetizing step of applying a second external magnetic field H2 so that an external magnetic field component forming an angle of more than 0° and less than 50 ° with a direction of the external magnetic field component applied in the first magnetizing step to a boundary between the first region R1 and the second region R2.
