Ring Thrower


Demonstrate the power of induction by shooting an aluminium ring up to 12 feet in the air. The ring placed over a coil of wire wound on an iron core is propelled into the air by eddy current repulsion when the coil is energized with an alternating current. However, when the solid aluminum ring is replaced by a slit aluminum or acrylic ring, there is no effect. Ready to use immediately after plugging into a wall socket. 115 VAC, 60Hz.
