Barlow's Wheel.

 

How can an electrically charged brass wheel spin, without the aid of a motor?

The secret lies in eddy currents. When electrified, this slotted brass disc sets up eddy currents throughout the structure. These "pockets" of electricity are attracted to 4 strong neodymium magnets, causing the wheel to spin.

Use this device to demonstrate the mysterious properties of eddy currents, and their effect on the world.
