Abstract: PURPOSE: An automatically controlled apparatus and method for shielding a reverse current using a current sensor are provided to automatically optimize a reverse current by inducing a reverse current to flow around a wire. CONSTITUTION: A magnetic field generating device(70) generates a leakage magnetic field(711) to be shielded. A current sensor unit(721) senses a current flowing in a coil of the magnetic field generating device. The current sensor unit transmits the sensed current signal to a current size sensing unit(722) of a controller block. The current size sensing unit senses the size of the current from the transmitted current signal. A phase detection unit(723) detects the phase of the current from the current signal detected from the current sensor unit. A shield current calculation unit(724) produces proper size and phase values of the shield current from size and phase information of the current.
