Yesterday I walked into class and my physics teacher had this huge spreadsheet up on the projector on our grades and mine still had a few blanks in it. He said that to make up for it, i should make an essay and a presentation on anything I like involving physics principles. He wanted the essay and the presentation on two different things and I decided I wanted to do a presentation on how electric guitars work. I hate physics, but I do want to pass this class and I've always wondered how electric guitars work. I don't play electric so i have no idea how they work so if anyone can tell me or give me some links to websites that might help me, I would greatly appreciate it.
This is easily found via google.

Electromagnets detect the vibration of strings and convert it into an electric signal which the amplifier turns into an audible signal and pumps out the speaker.

You are a girl ( I think). Just wear short skirts all the time and sit on teachers lap. A+

Basically the pickup function can be explained using Flemmings right Hand rule. (think its right anyway). Basically the pickups work by the strings moving over the pickups. The pickups are magnetised so it generates electric currents. Kinda like a really weak generator. I'd google it or try it on wikipedia

Will the pickups pick up sound from nylon strings then?

No. They have to be conductors. That's why the pickups don't pick up the sounds of your hand or your annoying little sister's screams.

They have to be a magnetic metal, Iron, nickel or cobalt, any other metal doesn't exhibit magnetic properties without an electric current.

Yeah, they have to be a metal that can be magnetized. Forgot to mention that.

Unless she screams in tune and the strings resonate...

*Ahem* Sorry about that. But he's right. Basically, the magnets in the pickups create a magnetic field. When you pluck the string, the motion of the metal string distorts the magnetic field (per the law darkstar mentioned, which is Lentz's law, I think), and this creates the signal that is sent to the amplifier.

I did my advanved higher physics investigation on the electric guitar. 'Factors affecting the pitch of a plucked string'. EASIEST. REPORT. EVAR.
physics is very interesting...Pickups are coils which work via electromagnetic induction...look it up!
