Abstract
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 are drawn together with the insertion of a magnetic field modifier. 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.

48. An apparatus comprising:
-
a pair of magnet members being spaced apart from each other; and a third member as a magnetic field modifier; wherein when said third member is moved to a critical position relative to said pair of magnet members by either moving into or departing from a magnetic field between said pair of magnets, said magnetic field therebetween is altered to such an extent that at least one of said pair of magnet members is displaced between a first position and a second position; wherein when said third member is removed from said critical position, a magnetic field therebetween is altered such that said at least one of said pair of magnet members returns to said first position; and wherein said third member is cyclically moved to and removed from said critical position to cyclically alter said magnetic field to induce cyclic movement of said at least one of said pair of magnet members between said first and second positions. - View Dependent Claims (49, 50, 51, 52, 53, 54, 55, 56, 57, 58)
