Swinging spokes kinetic magnetic amusement device
Abstract:
A magnetically actuated amusement device includes a supporting structure having a fulcrum which pivotally supports rigid suspending elements each having a permanent magnet at its outer end. The magnetic swinging elements are arranged in an arc, sharing a common fulcrum, such that they will repel neighboring swinging elements in the arc, the motion of the swinging elements being constricted to swinging in the plane containing the arc.
