Abstract
The method and apparatus for supplying power to a rotary element by magnetic induction. A magnetic induction device having at least one secondary induction assembly including a secondary winding is mounted on the rotary element. A magnetic flux is induced the secondary induction assembly, causing an induced alternating current in the secondary winding of the secondary induction assembly. The secondary alternating current is converting to direct current and is stored in an electrical storage device. A rotary cathode plater is disclosed as a particular application of the apparatus by which power is transferred to a storage battery or high capacity capacitor, without the use of wires.
