The homopolar motor is one of the simplest electric motors. They use electromagnetism to support motion and were developed by Michael Faraday in the 1800’s. Homopolar force can be explained using the Lorentz force. This force is caused by electric currents and magnetic fields that are perpendicular to each other, causing rotation.
In one of our past blogs, we showed you how to make a similar homopolar motor. The one we are designing today uses two magnets to create forward propelling motion instead of spinning. This motor will act like a small car, moving forward when placed properly. To get started with your DIY magnet car, you’ll need some supplies you can probably find in your kitchen, along with some magnets, of course! Continue reading
