Abstract
A toy that has a pair of wheel-like members mounted on a central axle. The central axle is a ferrous metal rod with a pair of small permanent or other magnets attached to each end of the rod. The two magnets are positioned so that like poles face each other in opposition and face the center of the rod. A non-ferrous support plate such as a flat piece of wood with a metal strip on its edges forms a track. The magnets associated with the axle causes the toy to achieve the effect of clinging to the metal strip portions of the track. When the device is placed on the track, it will roll along the track under the force of gravity while magnetically clinging to the track in any horizontal or vertical position of the track.
