EMF CANCELLATION APPARATUS USING REVERSE CURRENT

摘要

PURPOSE: An apparatus for shielding electromagnetic waves using a reverse current is provided to shield the electromagnetic waves by applying the reverse current around a wire. CONSTITUTION: A shielding coil(313) for a power supply device(310) is arranged on a shielding position in order to shield a magnetic field due to a current flowing in a power supply coil(312) of the power supply device. The shielding coil for the power supply device removes a magnetic field by compulsively applying the current in a reverse direction of the current in the power supply coil. The shielding coil for the power supply device is arranged in the shielding position in order to shield the magnetic field due to the current flowing in a current collecting coil of the current collector. The shielding coil for the current collector removes the magnetic field by compulsively applying the current in the reverse direction of the current in the power supply coil.
