With a strong magnetic field. When I worked for Western Atlas we had a Zapper that we plugged in and set the magnet into a cradle that was surrounded by an electromagnet. It was set for about 3 large pulses that would take a AlNiCo magnet from being so weak that it couldn't pick up a paperclip to strong enough to pick up a 25 lb weight. I am sure it would be the same type of operation but the poles would be oriented so that the N and S are perpendicular to the length of the rotor. I would like to know exactly how this is done also. Things like how many amps @ Volts and how many turns are in the electromagnet and what gaquge the wires are.

I suggested using Locktite for retaining sleeves to glue a rotor back onto the shaft after it came loose to a friend of mine and it worked great, but you have to heat it to over 400F to get it to seperate.
