Abstract
PURPOSE: The collector of transistor is connected to the positive side of diode bridge, and the emitter is connected to the negative side respectively. Then, the resistance and condenser's serial circuit are inserted into the collector from base. As a result, demagnetization is possible with no effect of power source voltage and external temperatures, etc.
