Abstract
A magnetic levitation device and method of levitating a magnet without mechanical restraining elements are disclosed. The levitation device comprises a first magnet with a polygonal, preferably square, periphery and a substantially planar upper surface magnetized normal thereto and a second magnet with an apparatus to rotate or spin the same. The second magnet is rotated or spun on a lifter plate disposed on the upper surface of the first magnet with like polar orientations of the magnets in confronting relation. When the lifter plate is raised above the first magnet the spinning second magnet levitates above the first magnet and the lifter plate and the lifter plate is removed from between the first and second magnets. The weight of the second magnet may be varied to change the height above the first magnet at which the second magnet levitates.
