Here is an extremely simple electric motor you can make for a science fair experiment to demonstrate how electric motors work, All you need is one AA battery, two safety pins, one small neodymium magnet, some very thin copper varnished 28 or 30 gauge SWG or AWG wire, and electrical tape. You will need to use some sandpaper or an emory board to take sand off the varnish where the wire contacts the safety pins. Also, even though the battery is only a AA battery, the wire can get extremely hot of it stops spinning, so be careful. This motor also drains the battery quite fast so have some spare batteries. Lastly, to prevent any fires, do not store the battery with the wire and most importantly, do not carry it in your pocket or you could be burned.
