TESLA COIL
PHY-00710
This hands-free Tesla coil is used to demonstrate the unusual propertiesof high-frequency electrical phenomena. This electrifying device teachesabout transformers, electromagnetism, resonating electrical circuits,electric inductance, capacitance, and electrical power transmission.Transmit electricity without wires. Watch light bulbs glow in your hand.Study the ionization of gases and the behavior of insulators andconductors. This powerful, compact apparatus is a completely safesource of high frequency high voltage electricity. Arcs to 30mm, illustrateits maximum output of 50,000 volts. Its design includes cord and plug;primary coil; secondary coil with 1000 turns of wire; and high impactresistance plastic housing that protects you from the spark gap. Fullyassembled. 220 volts operation (110 V operation on special order).Also Includes two antenna plates, small neon light bulb,mini discharge electrode and lamp socket.
