http://amasci.com/coilgen/ Build this ultra-simple AC electric generator from magnets, wire, and cardboard. (And a big nail!) Light a small lightbulb, or flash a red LED.This demonstrates how generators work. Now if you want a more useful device, use a small DC motor as a generator, since it has much better magnetics design. All motors are generators. Figure out how to spin a motor's shaft, and you can make a small powerful generator. Or... figure out how to convert the cardboard generator into a motor!

wbeaty, you are a very smart guy do you think perpetual motion exist? cause think with one of your generators you can light up a light bulb.well add in a motor and some type of drive system to the shaft(nail) and if added say 5 more of you generators you could possibly make enough current to run the motor nonstop, right? well to make it efficient you could have bearings and stronger magnates, along with more coils. i think it is possible with the right gear ratio to make it workright back soon

wow awesome instructions i wana try that bad

> can you tell me how much it producesThe light bulb needs at least 0.5 volts at .007 amps, or .00035 watts ( four milliwatts.)If you spin it very fast so the bulb lights brightly, then its 1.5 volts and 0.025 amps, or 0.0375 watts (about forty milliwatts.)It's not as simple to produce several watts needed by a normal flashlight bulb. You need supermagnets. Or add some iron parts made in a machine shop. Or just spin a small DC motor (it becomes a genrator.)

> what's that red thing called on :22 "Multi purpose nylon binding posts 4-pack" from Radio Shack. Or just binding posts from All Electronics, goldmine, etc.

how does the electricity pass??and if you do more rounds of wire wouldnt the resistance increase thus making it more difficult for the bulb to light???

crap it wont load.......

Thanks my son will love this.

No curve magnets make curved electricity; and straight magnets make straight electricity.

does a curve magnet will work on this?i dont have flat like bar magnet.
