A generator for producing electricity at high efficiency from mechanical energy includes a housing, a shaft mounted in the housing, an electrical coil positioned about the shaft and an annular, anisotropic magnet positioned about the shaft adjacent the coil. The magnet has a plurality of circumferentially distributed, alternating magnetic poles. Ferromagnetic flux plates are operatively associated with the magnet and the coil for establishing an alternating magnetic field through the coil as a function of rotation of at least one of the magnets, the coil and the flux plates.

[ What is claimed is:] [1.] An electric power generator comprising:a housing;a shaft mounted in said housing;a first electrical coil positioned about said shaft;a generally flat, annular, anisotropic magnet positioned about said shaft adjacent said coil, said magnet having a plurality of circumferentially distributed, alternating magnetic poles, each one of said poles at a radial location on one axial side of said magnet being of opposite polarity to a corresponding pole at said radial location on the opposite axial side of said magnet; andferromagnetic means operatively associated with said magnet and said coil and having at least one position for concurrently overlaying all poles of a common polarity for establishing an alternating magnetic field through said coil as a function of rotation of at least one constituent of a group of constituents wherein a first constituent comprises said magnets, a second constituent comprises said coil and a third constituent comprises said ferromagnetic means.
