Abstract
A magnetically actuated amusement device includes a supporting structure having side pieces which pivotally support rigid suspending elements each having a permanent magnet at its lower end. The magnets are arranged in a row, such that they will repel the next magnet in the row, the motion of the magnets being constricted to swinging in the vertical plane containing the row.
