I always wondered why the hell you would put a coin of wire inside a 
circuit. I mean, sure, if you put power through it, you can use it to 
pick up metal objects. But why would you have such a thing inside a machine?

Ah, but wait. When you turn the power off, the magnetic field collapses. 
And what do we know about coils of wire inside a changing magnetic field?

I *so* didn't see that one comming... People are way smarted then me. :-/

Still, the stuff about the Laplace transform was cool. Very hard to 
comprehend, but cool...

Oh, the *equations* are easy enough. Now try *solving* them... ;-)
