ABSTRACT:
A magnetically activated disc has a flat bipolar ring magnet mounted concentrically on the upper surface of the disc. The bottom surface of the disc has a protruding center point which provides an axis around which the disc can spin. The disc has a sidewall on the upper surface extending upwardly around the circumference of the disc to form an open cavity for holding a removable disc having a design imprinted on its upper surface. An external permanent magnet is manipulated so that its magnetic field acts upon the bipolar ring magnet, thereby causing the disc to spin around the protruding center point so that the disc with the imprinted design produces a desired visual effect.
