ABSTRACT:
A magnetically levitated spinning axle display apparatus having a base assembly and an axle assembly. The base assembly includes a base platform member having a plurality of base magnets that are disposed spaced apart along an upper surface thereof. The platform member has an upstanding wall forming an axle support member disposed at one end. The axle assembly includes a plurality of disc shaped magnets disposed spaced apart along the rod and coordinate with individual ones of the base magnets when a first or second rod end portion is engaged in abutting contact with the upstanding axle support member. The polarity configurations of the rod magnets and the base magnets are repulsive to one another to permit free floating levitation of the rod above the base and to generate a longitudinal lateral force sufficient to keep a rod end contacted with the upstanding axle support. A plurality of alternate embodiments are created through varying the shape configurations and polarity configurations for both the rod and base magnets. In another alternate embodiment, a single ring magnet is provided to the rod which is repulsed by a coordinate base magnet disposed along an upper surface of a base member. An upstanding axle support including a bore hole is provided to engage a pointed end of the rod to maintain the axle in a horizontally levitating position.
