This is a unique variation of the worlds simplest motor, the homopolar motor. The difference here is that both the AA battery and neodymium magnet are the rotating motor parts. The battery and magnet hang from the steel welding rod wire holder, and a copper wire controls the power.

For Homopolar Motor Kits, with 3 magnets and 6 feet of copper wire, order from the good folks at the American Stirling Engine website: http://www.stirlingengine.com/ecommerce/product.tcl?usca_p=t&product_id=93

I order neodymium super-magnets from :

  • The magnet is a 9/ ...

    The magnet is a 9/16 inch neodymium supermagnet that came from a shake-flashlight. Find a dollar store that sells shake-type flashlights and haggle to get the burnt-out ones cheap.

    It will likely be hard to find that size magnet without ordering on-line at a place like K&J Magnetics,(link in the "more info" box >>>) but you might try a craft store for 1/2 inch x 1/8 inch neodymium disc magnets and stack them. Don't try the brown crap magnets, they won't work.

  • Copper or silver ...

    Copper or silver wire will work. Steel wire will not work, because it sticks to the magnet.
