Looking for a design to build a AC magnet which can attract ferrous metals? Has anyone built one of these?
I am pretty sure that you can't out of an alternating current. It is the "one direction" voltage that dc had that makes the ferrous molecules in metal to align and become magnetic. So you'd need to change the ac to dc by using a converter like a wall adapter for electronics.

Oh, would you look at that... I had no idea you could use AC for that.
