Abstract:
1. A method related to making at least one wound magnetic field coil for a rotary electric device, such at least one wound magnetic field coil comprising at least one magnetically conductive core, said method comprising the steps of: a) providing at least one electrically-conductive thin-film battery cell; and b) winding said at least one electrically-conductive thin-film battery cell around the at least one core to form at least one magnetic-field-producing battery-coil; c) wherein such at least one electrically-conductive thin-film battery cell is structured and arranged to produce electrical current derived from at least one electrochemical process; and d) such electrical current is usable to generate at least one magnetic field within said at least one magnetic-field-producing battery-coil.
