The source for the magnet would need to be external to the controller (so as not to draw excessive currents.) and the relay contacts need to be able to handle whatever current the electro magnet requires.
I was checking that too. If a you could make a switch that was controlled by PWM, the PWM ports are designed to take up to 4 amps. By that time, though, it would be easier to just to go with a relay.
Just food for thought.

I love to take things apart. The fact that they work better when I put them back together it just a bonus.
