Build Your Own Homopolar Motor

This is a great instructional video for anyone who is looking to impress! You need just three parts; a new AA battery, some copper wire and a magnet that is all you are going to need. Simply bend the copper wire so that there is a circular top that goes over the positive part of the battery, connect it all together and you are away!

Check this video out and just think how impressed your family and friends would be to see something like made right in front of them, with no tricks or gadgets to assist!
