ABSTRACT:
A device for magnetizing multipolar permanent magnet bodies employs a supporting structure comprising a solid block, or a series of superimposed sheets, of electrically insulating material, which may be of fiberglass, with prepared apertures to receive the electrically conductive magnetizing winding; the apertures may be arranged to firmly support the winding to prevent displacement despite the strong magnetic fields generated by a high-current impulse discharge, and the winding can be arranged to produce a variety of polar patterns on flat magnets or, by providing a suitable opening in the supporting structure, on cylindrical magnets.
