Abstract:
1. A device for heating an object by an electromagnetic induction, wherein the device comprises: at least one rotor arranged to heat the object, said at least one rotor comprising at least one permanent magnet, and a stator for providing varying magnetic field arranged to interact with at least one permanent magnet of said at least one rotor and causing said at least one rotor to rotate, wherein at least one permanent magnet of said at least one rotor is arranged to provide varying magnetic field and eddy currents within the object when said at least one rotor is rotated so that said object is heated by the electromagnetic induction generated by said varying magnetic field and eddy currents, and wherein the device comprises at least one additional rotor with at least one magnet, wherein at least one magnet of said additional rotor is used for heating at least one object by the electromagnetic induction, and wherein the device either comprises: a) driving means for providing rotating force for rotating said additional rotor, the rotating force being derived from the rotor rotated by the varying magnetic field induced by the stator, or b) an additional stator used for rotating said additional rotor.
