School House Picture Holder

Homopolar Motor

Homopolar Motor School House

Show your teacher that you appreciate her by purchasing her a Homopolar Motor School House. This is a great gift, because not only does it move, but it can hold a note or a favorite picture of a loved one.

But wait, there's more! It's also educational. Kids you can explain to your teacher how it works. How does it work you ask? Electricity flowing through the wire create a magnetic field causing the wire to rotate around the battery. The wire tips are connected to the positive and negative ends of the battery. The top of the wire has a small indention to hole the message or picture.
