Product Information

In this dramatic demonstration, a solid aluminum ring immediately shoots 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. This updated version of the apparatus eliminates uncertainties and hazards often associated with the experiment. An automatic one-shot timing feature prevents the coil from overheating and ends repetitive shots. In addition, all current carrying components are insulated to prevent accidental contact. You can also use the device to illustrate induced current when a small coil of insulated wire connected to a lamp is placed over the mail coil — with the press of a button, the lamp lights briefly. Ready to use immediately after plugging into a wall socket, this ring thrower includes an operation and experiment manual. 115 VAC, 60Hz. Size: 46 cm H x 20.3 cm dia.
