A magnet molding tool for controlling the orientation of magnetic particles in a polymer bonded magnet during injection molding. A magnet mold has a mold cavity. A flux generator is connected to the magnet mold for applying a magnetic field in the cavity. An upper plate is attached to the magnet mold to modify the magnetic field in the cavity such that the orientation of the magnetic particles varies proportionally to the dimensions of the plate.
