A bonded magnet is a kind of magnet which is made by mixing a certain permanent magnetic property magnetic powder with a certain proportion of binder and according to a certain molding process. If an orientation magnetic field is applied during the reshaping process, the easy magnetization direction of the magnetic powder is in the same direction in the magnet, which is an anisotropic bonded magnet, otherwise it is an isotropic magnet. The forming method of the bonded magnet is various, including compression molding, injection molding, extrusion molding, and calendering.
