TEMPERATURE LIMITED HEATER UTILIZING NON-FERROMAGNETIC CONDUCTOR

摘要

A heater is described. The heater includes a ferromagnetic conductor (242) and an electrical conductor (244) electrically coupled to the ferromagnetic conductor. The ferromagnetic conductor is positioned relative to the electrical conductor such that an electromagnetic field produced by- time-varying current flow in the ferromagnetic conductor confines a majority of the flow of the electrical current to the electrical conductor at temperatures below or near a selected temperature .
