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.

Description

For ordinary magnets, iron bars, strips etc. Consists of a 250 mm long solenoid wound with insulated copper wire and mounted on a base, with switch and 4mm terminals. Operating voltage is 12 V A.C. or D.C. At 6A max.
