ABSTRACT:
To provide a magnetizing apparatus and magnetizing method in which, even in preparation of a ring-shaped permanent magnet having a narrow magnetization pitch with multiple poles magnetized on an extremely small diameter, sufficient magnetization and high magnetization quality can be achieved and powerful magnetization can be carried out efficiently and quickly at low cost.A permanent magnet magnetizing apparatus includes a heating section10, a magnetizing section12axially disposed as a discrete structure from the heating section10, and a holding member22for holding magnetization object20and movable relative to the heating section and the magnetizing section. The magnetization object heated in the heating section is transferred to the magnetizing section and is magnetized therein.
