ABSTRACT:
A new inductor, coating, and method adapted to improve the directional control of magnetic flux of an inductor. The method may include using a fluidized bed or other like methods to coat an appropriately masked inductor with a coating composition comprised of a low reluctance material and a binder. The low reluctance material in the coating composition may include such materials as carbonyl iron powder or the like, whereas the binder may comprise a polymeric resin or the like. The present coating composition increases the directional control of magnetic flux, and efficiency of the inductor by selectively distorting the magnetic field and thereby increasing and intensifying the flux density on a subject workpiece being induction heated. The invention is also believed to be usable in improving directional control of magnetic flux in other electrical conductors.
