Abstract

See full text

A heater may include an electrical conductor. Applying alternating current to the electrical conductor may resistively heat the electrical conductor. The electrical conductor may include an electrically resistive ferromagnetic material. The ferromagnetic material may at least partially surround a non-ferromagnetic material. The heater may provide a reduced amount of heat above or near a selected temperature. An electrical insulator may at least partially surround the electrical conductor. A sheath may at least partially surround the electrical insulator.
