A homo-polar motor is basically a battery, some magnets, and wire. Wire is not available to me and won't be. I'm 13 years old and unable to go out and by wire at Ace Hardware. My mom and step dad work too much and don't have the time to take me. To make one of these motors you stick the magnets to the negative end of the battery, then coil wire* around it, then spin it. The magnet helps the coil complete reps, and the battery is for electricity to keep it running. I mean cutting a coat hanger and shaping it to coil around the battery. Thanks.
