Homopolar motor

free html hit counter

Make a 10,000 rpm motor in less than a minute using only one drywall screw, one 1.5 V alkaline cell, six inches of plain copper wire, and one small neodymium disk magnet. (Any metallic magnet which has a north pole on one flat face and the south on the other will do.)
