A magnetic field based mechanical apparatus is disclosed. The apparatus is based on coupled attracting or opposing magnets in conjunction with the insertion or removal of a magnetic field modifier. In the preferred embodiment, two repelling magnets (11, 12) are drawn together with the insertion of a magnetic field modifier (13). The field modifier may be another magnet having an opposing pole. Removal of the field modifier returns the forces to their original states. This oscillating motion may be driven with a low energy and/or small power supply. The resulting motion of the opposing magnets can drive mechanical system such as a linear, gear, ratchet, or reciprocating drive. |
