How to Make a Homopolar Motor

Disclaimer: You follow this tutorial at your own risk. I will not be responsible for any injuries, problems, or trouble you get into for following this tutorial. Project not recommended for children under 13 years old. Minors should work under adult supervision.

Neodymium magnets are very strong. The magnet I was using can hold approximately 120 pounds, that's how strong it is! Please be very careful. 2 neodymium magnets can crush bones! Neodymium magnets can wipe credit cards, interfere with electronics, and even break electronics! Keep all electronic equipment and credit cards at least 3-5 feet away from the magnet! If you use a pacemaker, this project isn't for you.

The motor spins because of the Lorentz force. :) Physics is cool. :P

Here are links to some of the materials you'll need:
