ABSTRACT:
A magnet assembly for producing a varying magnetic field is provided wherein a plurality of permanent magnets are interposed between two members which are constructed of a ferromagnetic material. Each of the magnets is rotatable and has a north and south magnetic pole. Each of the magnets is disposed so that the north magnetic poles of the plurality of permanent magnets have a common magnetic orientation with respect to the first member. An orienter, such as, for example, a ring gear and pinion arrangement, is coupled to the magnets to change their common magnetic orientation with respect to the first member. The magnetic field projected by the assembly varies as a function of the orientation of the magnets.
