1. An apparatus, comprising:

  • a base comprising a support surface;

    a first electromagnet disposed in the base and configured to generate a first magnetic field at the support surface, wherein the first electromagnet comprises;

    a first coil formed from a first electrically conductive wire, wherein the first coil forms a first loop from a viewpoint perpendicular to the support surface, wherein the first electromagnet has only the first coil, anda voltage generator coupled to both ends of the first wire;

    a controller disposed in the base and configured to control the first magnetic field generated by the first electromagnet according to a predefined gameplay motion pattern configured to induce an entertainment object proximate to the support surface to perform a desired action causing spatial separation of the entertainment object relative to the support surface; and

    a second electromagnet configured to generate a second magnetic field at the support surface according to the predefined gameplay motion pattern, wherein the second electromagnet has only a single second coil formed from a second electrically conductive wire, wherein the second coil forms a second loop from the viewpoint perpendicular to the support surface, and wherein the base comprises at most two coils;

    wherein the first coil is disposed a first distance from the support surface, and the second coil is disposed a second distance from the support surface, wherein the first coil overlaps the second coil relative to the viewpoint perpendicular to the support surface.
