摘要

A heater (20) employs a ferromagnetic or like material heated by a varying magnetic field to heat the ferromagnetic material wherein the ferromagnetic material has a large cross section (D) comprised of many members (12) of small cross section (d) insulated (16) from one another and wherein for medical applications each member may be surrounded by a heat conductive electrically conductive coating (14).
