Instructions
Plug in the magnet zapper into an outlet, then turn it on.
Insert the motor can, which is the outer shell of the electric motor, into the receptacle slot on the magnet zapper. The motor can has magnets mounted inside of it.
Use the readout on the front of the magnet zapper to indicate the direction of the motor's magnetic polarity. If it's the correct orientation, press the start button to begin zapping the magnets. Turn the motor can 180 degrees to zap the magnets with opposite polarity.
