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.

Abstract: A permanent magnet armature is arranged to be moved initially in spaced proximity to an induction coil connected in an electric circuit across the series arrangement of a source of electric potential and an electronic switch such that when the moving magnetic field of the magnet cuts the coil turns the resulting induced current operates the switch momentarily to connect the source of electric potential across the coil. The resulting current flow through the coil produces a magnetic field which is imposed upon the moving magnet such as to accelerate its movement. An RC time constant circuit is connected across the coil to establish the time period of battery connection across the coil.

Abstract: A spinning top game includes a spinner mounting a permanent magnet, a housing having a dished top base for supporting the spinner above an induction coil in the housing connected in an electric circuit including a source of electric potential and an electronic switch so arranged that when the spinner is rotated on the dished base, the moving magnetic field of the magnet cuts the coil turns and the resulting induced current operates the electronic switch intermittently to connect the source of electric potential across the coil, the resulting current flow through the coil producing a magnetic field which is imposed upon the moving magnet spinner such as to accelerate its movement.
