Patent ID: 7476989

Claim:
A dynamic magnet apparatus for generating electrical power adapted to connect with a rectifier and accumulator, comprising: a hollow elongated carrier including two opposite ends, at least one end thereof forming an opening, the carrier wrapped around by a number of coils; at least one slidable magnet disposed in the hollow elongated carrier; a pair of fixed magnets positioned at outer surface of the opposite ends of the hollow elongated carrier, each fixed magnet being in polar opposition to the slidable magnet, with facing ends of like magnetic polarity; a supplemental weight attached to the slidable magnet; and a cover covering the opening; wherein the slidable magnet, which cooperates with the supplemental weight and therefore has more inertia, slides back and forth in the carrier more easily and increase the efficiency of electromagnetic induction in the coils due to the magnetic field lines cut by the turns of the coils completely.
