I'm trying to build a small electromagnet of a 5v breadboard i had set up, but I've run into some troubles. It doesn't work, and I'm trying to figure out if I just need to pump more current through it or if the core I'm using is made of the wrong materials. Does it have to be straight up iron? Or will anything attracted to a magnet work? Is there a way to tell if something would work or not?
