Subject: How would you create a controlable electric force?

I am working on a science project and I have checked many sites. I was 
wondering how you would create a small simple electric creator (generator?), 
but generates a large jolt of electricity. I have seen a post about a coiled 
copper wire and a magnet. This sounds like an interesting idea - but if you 
rotate the magnet fast enough, would it actually create a lethal electric 
charge? (Yikes!)And if you stop spinning the magnet or take out the magnet does 
the electric charge discharge?
