Abstract

An electromagnetic energization system is disclosed wherein a stray alternating magnetic field is generated by conducting a current through a discrete (i.e., indefinite) length of wire or rod instead of a fine wire winding. A permanent magnet rotor is disposed so that it intersects the stray field in an appropriate manner to effect rotation of the rotor, which rotation is usable to energize or propel an object located in the vicinity of the conductor. The conductor, usable with toy vehicles and multiple track segments, is of single continuous length or is series connectable by means of quick disconnect electrical connectors. The permanent magnet rotor can be incorporated in a planetary gear system to achieve speed reduction between the spinning rotor and a drive mechanism for a mobile object. The orientation and effect of the magnetic field is controllable by varying the polarity of the current passing through the conductors, the frequency of the alternating current used to generate the field, and the current.
