Main Question or Discussion Point

So you have a current flowing through a wire. How do you go from that to, say, spinning a fan blade when you flip a switch?

I took physics but they were more interested in teaching us obscure calculations than actually explaining practical material. If you want to know the total resistance of a circuit I can do that, I just can't tell you what on earth you will be doing with that circuit.

Yeah, wikipedia and howstuffworks.com are both pretty good places to get basic information about how things work:

Yes we obviously learned about inducing magnetic fields with a current in physics, I just didn't know that that was how most devices worked.
