Abstract

An apparatus for producing an alternating magnetic field by arraying a plurality of charged storage elements e.g. capacitors and a plurality of connecting elements e.g. transistors spatially around a physical area of magnetic field generation and in such a series circuit that electric current flows in one direction through the storage elements and in alternating directions around the physical area; and with pairs of the connecting elements interconnected with over-voltage protection elements.
