Abstract
To contribute to the size reduction of electromagnetic devices, a multipole magnetizing method for Nd-Fe-B isotropic bonded magnets using a heating system without any magnetizing power supply was examined. After rapidly heating above their Curie temperature, the magnets are magnetized during cooling in the presence of a magnetic field generated by a set of Sm-Co permanent magnets. The level of magnetization can be tailored by variation of the final temperature to which the magnets are cooled in the presence of the magnetic field. Due to the heating process, the magnets show excellent thermal stability.
