My son has built a homopolar motor and we can not figure out the science reason for the following:
When the magnet is flipped over the copper wire spins in a different direction, why????

Hello there,

I do not know much about how homopolar motors work, but I think this question will be better to pose to the experts in the physical sciences forum--they may be able to better explain this phenomenon to you!

Best,
Connie
