Alternating current changes the orientation of the electromagnetic field by rapidly switching directions, helps to demagnetization.
Alternating current changes the orientation of the electromagnetic field by rapidly switching directions.
Because providing an electrical field (electromagnet) is one technique to create a magnet, it stands to reason that you can use alternating current to remove magnetism as well.
To do this, an alternating current (AC) current is sent through a solenoid. Begin with a greater current and gradually lower it until it is zero.
The magnetic dipoles strive to position themselves according to the field, but because it changes, they become randomized. Due to hysteresis, the material's core may retain a modest magnetic field.
Hence, alternating current changes the orientation of the electromagnetic field by rapidly switching directions, helps to demagnetization.
