Abstract: An induction heating device for heating electrically-conducting material to temperatures of up to at least 300.degree. C. The device comprises an open core of ferrite material. A coil of Litz wire is wound around the core. A power source is connected across the coil to produce an excitation current in the coil, within a frequency range from 12 to 25 kHz, to generate a variable magnetic field when energized. Magnetic flux concentrator tubes of electrically-conductive material are disposed about the coil and close to the core embedded in a thermo-conductive electrically-insulating, material in the intend of maximizing the useful flux. A cooling fluid circulates through the concentrator tubes for cooling the tubes, the core and the coil. An induction zone is defined by said magnetic field generated between the opposed poles of the core and penetrating at the surface of the body to be heated. The body is heated by the eddy currents generated by the variable magnetic field on the surface.
