is the special magnet necessary or can you use any normal magnet?

It's too inefficient for any real use.

My roommate and I built one of these after watching the video. Oh, the things we do to get out of doing homework.

Yes, but that wouldn't make logical sense. Remember that this is just a motor powered by a battery. What you're suggesting is to connect a battery powered motor to a generator to create electricity. Why not simply use the battery for a power source?

maybe using the battery would create MORE power.
