Abstract
A magnetization method according to one aspect of the present disclosure, which is a method for magnetizing magnetic bodies in which at least a first magnetic body, a second magnetic body, and a third magnetic body are aligned, includes a heteropolar magnetization process. In this process, heteropolar magnetic fields are generated in a first magnetization yoke and a second magnetization yoke that are opposed to each other in a radial direction with a first magnetic body before magnetization interposed therebetween, and heteropolar magnetic fields are generated in a third magnetization yoke and a fourth magnetization yoke that are opposed to each other in a radial direction with the third magnetic body before magnetization interposed therebetween. In the heteropolar magnetization process, an amount of magnetic flux flowing through the first magnetic body is made larger than an amount of magnetic flux flowing through the third magnetic body.
