not to rain on ur parade or anything, but adding nail polish may keep tha safety pins from connecting to tha wire. but its pretty cool anyway   :)

Yes that is the point. You add nail polish to half the conductor so the circuit opens for every half rotation and the electric field collapses. That way the coil doesn't slow down from the magnet. It would slow down because as it rotates it's orientation changes and the opposing poles start distancing while the similar poles start approaching each other resulting in an opposing force.

Is it possible to use alternating current to make it work? If not, how do you make the simplest AC motor? Regards.

where do I get the axle it could easily work?

Have you tried it because it doesn't work?

any idea on what kind of power it can make? I am trying to build a small car-like thing and wondering if this would work. obviously I would have to shrink the battery and the screw possibly, but I think it is possible. any clues?

This is a pretty elegant way to make a simple electric motor. I made an electric motor ages ago as a science project and I used a 9volt battery and had to improvise a brush system. Pretty overkill for something that just has to spin. The nail polish eliminates the brush issue which cuts the power in half, but it much simpler.
