ABSTRACT:
A magnetic spinner toy includes a plurality of spinner bodies mounted one adjacent another on a support base for independent rotation. A plurality of permanent spinner magnets are mounted on each spinner body at circumferentially spaced positions for rotation closely adjacent the spinner magnets of the adjacent spinner body. The magnetic poles of the confronting surfaces of the spinner magnets of adjacent spinner bodies are either of like polarity, whereby to repel each other, or of unlike polarity, whereby they attract each other. A pair of permanent levitating magnets are mounted one on each spinner body and the other on the support base with the confronting faces of the pair being of the same polarity, whereby to repel each other and thus maintain the spinner body spaced from the support base to eliminate frictional engagement between them. A battery-operated electromagnetic drive mechanism may be associated with at least one spinner body for actuation by movement of the spinner magnets of said spinner body to move said spinner body by magnetic repulsion, whereby to extend the operating time of the magnetic spinner toy.
