(under subclass 58) Propelled racing wherein the object includes a magnet, electromagnet, or magnetically attractive substance, and, further, wherein the means to apply mechanical force to an object to be raced includes means external to said object for causing a magnetic force of attraction or repulsion between the object-carried magnet, electromagnet, or magnetically attractive substance and the external means sufficient to move the object.
(1) Note. The means for applying a magnetic force to the object commonly includes another magnet with additional means to move the other magnet along a race course to move the object along. However, this definition encompasses other means for applying magnetic force such as, for example, a plurality of stationary, separately energizable electromagnets spaced along the race course.
(2) Note. Magnetic propulsion under this subclass is intended to include only direct magnetic propulsion of an entire object by magnetic forces acting between the object and structure external to the object, as opposed to a magnet force acting entirely within the object such as by, for example, an object-carried electromagnetic rotary drive motor for driving an axle or wheel.
