    cool

    i love your idea lol!

    I kind of like it

    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.

    nice, i am searching this type of site.

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