Energize electromagnet coil for 0.5 second.
Pole of Alnico magnet is inverted.
Neodymium magnet and Alnico magnet become homopolar.
Magnet core turns to a powerful magnet to adhere
the workpiece.
At unclamp (Demagnetized)
Energize electromagnet coil for 0.5 second.
Pole of Alnico magnet is inverted.
Magnet line of Neodymium magnet and Alnico
magnet does not go out from the surface of magnet
core. Thus it unclamps the workpiece.
