DEMAGNETIZER FOR ELECTRIC EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive demagnetizer which can be applied to any kind of electric equipment and can prevent the leaking out of a magnetic field generated from the electric equipment. SOLUTION: Closed-loop coils 1 made of conductors are respectively provided in the enclosure 2 and doors 3 of a refrigerator R1 and, when a magnetic flux generated from electric parts housed in the refrigerator R1 passes through one of the coil 1, an induced electromotive force is generated in the coil 1 by the law of electromagnetic induction and the force generates a magnetic field. The generated magnetic field prevents the leaking out of the magnetic flux generated from the electric parts by compensating the magnetic flux.
