Magnetic means and circuits for efficiently conducting and directing flux to a flux emergent surface, such as the pole of a motor pole piece, in which flux produced by one or more permanent magnetic sources matched in reluctance to a working air gap is directed through an essentially continuously curved convex surface of a volume of magnetically permeable material significantly greater in area than the area of the working air gap, with the flux from the magnetic source(s) is generally everywhere normal to that surface.
