hi everyone:
here's the deal: I'm willing to go through and experiment with all of this stuff, but i want to try to understand it first. I know how electromagnets work KIND OF, and by kind of I mean the basics. What I'm having trouble with, just because I don't understand it, is why put magnets under the steel core? I have a small steel core and some wire ready for winding, but I'm wondering what magnet configuration makes the most sense, if it matters at all, and above all else, WHY???
