Looks like your typical washing machine part. And yes, lots of hold
power when the pole pieces touch.

Check to make sure it can pull in fully and that the poles are not
cruded up. It looks like it only needs some cleaning and TLC.

Serious case of corrosion there. No telling how much surface crud
on the sliding parts.

There is only one coil.

Of course, but we still have to listen to Maynard's view of multi-
windings and embedded diodes.


What else do you expect from 'Skippy - V2.0'? He also thinks
Electret microphones are crystal microphones, and that you can easily
change the bandgap in LEDs to adjust the color. He's a real, no class

Not sure about the flamewar going on here, but it's actually not hard to
get a LED to change colors. Get some liquid nitrogen and try it out.
