I'm going to show you how to make a copper wire spin with only a battery and two magnets!
Step 1: Materials
You will need-
-A Battery (can use AA or D battery)
Step 2: Assembly
You will first put your two magnets on the negative side of the battery and then bend your wire like in the picture. Although, you can switch your magnets to the positive side if the negative doesn't work. Make sure that the end of your wires touch the magnets as you balance your copper wire on the top of the battery.
Step 3: Finished!
If you had followed all of the directions correctly, then your homopolar motor should function, and the copper wire should spin. It may take a while, but you will get it.
