Patent ID: 8330314

Claim:
A magnetic device comprising: a first wheel having a first rotational axis, the first wheel further having a plurality of first magnets; and a second wheel received at least in part within the first wheel, the second wheel having a second rotational axis that is generally perpendicular to the first rotational axis of the first wheel, the second magnetic wheel having a plurality of second magnets, the configuration of the plurality of first magnets and the plurality of second magnets creating magnetic fields that cause one of the first and second wheels to rotate when the other of the first and second wheels rotate; wherein the plurality of second magnets are located on a first surface face of the second wheel that forms a plane that is generally perpendicular to the rotational axis of the second wheel; and wherein the second wheel has a second surface face that is cylindrical in shape extending parallel to the rotational axis of the second wheel, a plurality of fourth magnets coupled to the second surface face.
