An optimized homopolar magnetizing fixture consisting of four magnetic pole pieces was developed with the aim of achieving a focused magnetic flux on the surfaces of Nd-Fe-B alloy-based permanent magnets, and thus enhancing the magnetic flux density. In this fixture, only the transverse pieces involved coils providing the same magnetic poles in response to a pulsed current. Rectangular anisotropic and isotropic bonded magnets as well as sintered magnets, having dimensions of 6 mm © 12 mm © 24 mm or 6 mm © 12 mm © 16 mm, were magnetized to multipoles using a prototype fixture in conjunction with a pulsed power source. As a result, the magnetic flux density perpendicular to the surface (B z ) was increased by 52% relative to that of conventional simple magnets containing the same volume of magnetic compound, with the front and back surfaces magnetized to opposite polarities. In addition, the B z polarities of both the front and back sides of the magnet were determined to correspond to N-poles. The distribution pattern of B z led us to conclude that the enhanced B z and the equal polarity on both sides can both be attributed to the cusp field resulting from the flux generated by the transverse coils of the magnetizing fixture.
