Abstract
An induction heating device having a hollow cylindrical body made of electrically conductive material, at least one primary induction coil and at least one auxiliary induction coil, the at least one primary induction coil and the at least one auxiliary induction coil being arranged in the cavity of the cylindrical body such that, by means of the at least one primary induction coil and the at least one auxiliary induction coil, first and second magnetic fields, respectively, can be produced in the cylindrical body. The at least one auxiliary induction coil and the at least one primary induction coil operate such that the second magnetic field, at least in one area of the cylindrical body, counteracts the first magnetic field. A corresponding method of operating such an induction heating device, and also a processor for processing a recording medium, having such an induction heating device, are also provided.
