Abstract
This invention relates to energy harvesting of electrical energy by the change in a magnetic circuitous permeability path for magnetic lines of force that move through a coil of wire to induce, by Faraday's Law of Electromotive Induction, an electromotive force at the coil winding terminals of an associated coil. An abrupt, substantially instant change generated by a magnet's axial or angular mechanical and magnetic contact or dislocation through instant movement of the magnet by magnetic unlike pole spring back attractive force action with a high permeability stationary hollow or solid magnetic metal core centered in a coil bobbin with a wire wound wire coil providing efficient electrical generation therefrom.
