Abstract
PURPOSE:To perform accurate magnetization and make a magnetizer compact by applying pulse-shaped current to a coil inside a mold and magnetizing the magnet material at flow status. CONSTITUTION:Magnet material 6 is injected into the cavity 5 of a mold 2 through a runner 7. The magnet material 6 mixes magnetic material powder such as barium ferrite, strontium ferrite, etc. with the mixture in which valcanizing agent, plastic agent, stabilizer are mixed with powdered or pellet-shaped rubber or synthetic resin, as required. Then, while the magnetic material 6 flows, pulse-shaped magnetized current is applied to the coils of which are arranged on both sides of the circumferential section for the disk-shaped magnetized yoke 3 provided in a mold 2 once or several times and a ring-shaped magnet is obtained. By arranging a magnetic body 8 on the outer surface of the cavity 5, magnetized magnetic flux can effectively be used and high magnetic flux density be obtained.
