How do you get the coil to keep spinning if you completely remove the enamel from both sides of the wire? I would think the coil's magnetic field would simply alight with that of the permanent magnet's and just sit there. In order to spin the current through the coil has to stop for at least half the cycle.

You forgot to mention one requirement : Gravity :-)

I don't know about you, but I'm not planning on going where there's no gravity any time soon. ;-)

Why do you need gravity?? Just to keep it on the contact points?

Any photos or stills from the video? I am no a connection that can not view streaming video, not because of the lack of bandwidth but the fact that the service I have is so crap, most I get os about 108kbps average on a service they sell as T1 over 3G/HSDPA connections. So some stills would be nice to see.

I think this is the simplest one.

What type of wire did you use? Would that green craft wire stuff work too? Because yours is copper, and I think the craft wire is something like aluminum, or zinc.

author

i know you commented a long time ago but in case your still wondering and didnt try it out, aluminum should work. not sure about zinc though as long as the metal conducts electricity.

Is there a desired amount of winds you need to make? It is a great project, thanks a lot.

I love this. It's easy. Anyone could make this. You could make this into a desktop fan perhaps! And use a rechargeable battery. I have some scrap copper wire in the house from some renos. Would that work?
