Någon som har tips och länkar hur man löser det. I gamla TVn var det ju en spole och ett PTC-motstånd
AUTOMATIC DEMAGNETIZATION
Demagnetization of the chuck is accomplished by reversing the polarity and gradually reducing the output
voltage of the control unit. The primary advantage is
that both the magnetic chuck and the workpieces can
be completely demagnetized. Thus workpieces can be
easily removed from the chuck.
Depending on the type of steel, different demagnetizing programs can be selected
