HOW TO MAKE A HOMOPOLAR MOTOR!

In this video I'll show you how to make a simple Homopolar motor using a battery, copper wire and 6 button magnets. Current passing through the circuit has a rotating field around the wire. Because of how you bend the wire, the force of the magnetic field around the wire points in opposite directions at either end of your motor so it spins. The same principle works for larger electric motors, they just have a lot more wire in the coils and consume more energy so they can produce greater torque and power.

I did not know motors could be made like this!
