PURPOSE:To obtain a large calorific power by a small electric current by causing the self heat generation due to eddy current in a heating unit through the electric conduction into an coil and heating a driving body. CONSTITUTION:When a coil 1 is brought into conduction, magnetic force lines are generated radially from the coil 1, and passes through a heating unit 3 arranged in the vicinity of the coil 1. When the magnetic force line passes through the heating unit 3, a Joule heat is generated in the heating unit 3 by the eddy current induced by the magnetic force lines, and the temperature of the heating unit 3 sharply rises. Since the heating unit 3 is put into self heat generation, a large calorific power can be obtained from the heating unit 3 by a small electric current. |
