Abstract
A configuration for producing electrical power from a magnetic field includes a three-dimensional winding configuration formed from a central core of a magnetic material on which at least three windings are fitted. The windings have winding axes each disposed at right angles to one another and intersecting at a common point. Each of the windings is connected to a rectifier. Each of the windings is, preferably, connected to a resonant capacitor to form a resonant circuit.
