ABSTRACT:
A method and apparatus for manufacturing a rare earth magnet is disclosed. In a first step, a compact is produced by compacting rare earth alloy powder in a predetermined space in an orienting magnetic field. Next, a demagnetizing process is performed for the compact, and the compact is ejected from the predetermined space. Then, a additional demagnetizing process is performed for magnetic powder adhering to a surface of the compact by applying an magnetic field to the compact after the compact is ejected.
