description Disclosed are a method for pulverizing a waste magnet and a waste magnet powder produced by the method. More particularly, disclosed is a method for efficiently producing a waste magnet powder having a small average particle size by pulverizing a raw material containing a hydrogen-occluded rare earth metal before dehydrogenation of the raw material.
