Apparatus and applications for magnetic levitation and movement using offset magnetic arrays

Repulsive force created by actuated permanent magnets is used to levitate and transport heavy loads. A bed of permanent magnets is selectively actuated to levitate an array of magnets positioned above the bed, such that the magnets in the levitated array are opposed to the actuated magnets, and of the same magnetic pole, thereby creating a repulsive force. The actuated magnets are vertically offset from magnets in the bed of permanent magnets that have not been raised, thereby imparting maximum levitation forces to the magnets in the levitated array. These systems can levitate and transport objects over level or sloped surfaces, in a straight path or along curves and corners. A bed of magnets can be attached to the floor, or to a set of moving decks that rearrange themselves in a desired path. Our systems can simulate walking or running, similar to a treadmill or virtual gaming platform.
