ABSTRACT:
A demagnetizing power source for producing an attenuation alternating field to demagnetize a magnetized substance. This power source is provided with a memory circuit for sending actuating signals to a polarity changing-over circuit to change over the polarity of direct current supplied from a rectifying circuit to an exciting coil. In the memory circuit are stored a plurality of preset demagnetizing patterns. The polarity changing-over circuit changes over alternatively the polarity and gradually decreases the change-over cycle according to the selected demagnetizing pattern.
