Barlow Wheel
Description
This apparatus spins an electrically charged brass wheel spin, without the aid of a motor. When the wheel electrified by a voltage source (battery), the slotted brass disc sets up eddy currents throughout the structure. This electricity is then attracted to 4 strong neodymium magnets, causing the wheel to spin.
