Eisco Labs Induction Coil - 50mm Spark - 11.5" Long, 7" Wide, 6" Tall mL

• 50mm Spark Induction Coil
• Includes Coil, 2 Spark Rods, Shaker, Reversing Switch, On/Off Button and Power Sockets
• Provides very high voltages (several tens of thousands of volts) from a DC source.
• Simply connect a power supply 9-12V / 5A maximum. The continued production of sparks is obtained by adjusting the shaker and voltage
• Great for physics demonstrations and experiments

The induction coil provides very high voltages (several tens of thousands of volts) from a DC source. The principle is based on a step-up transformer comprised of a primary winding, a few tens of turns, and a secondary winding, hundreds of thousands of turns. To produce permanent sparks, it is necessary to cut the current flowing in the primary winding with a shaker (electromagnetic bell).

The induction coil stands 6" tall, 11.5" wide and 7" long. Each spark rod measures 5.25" long and 2.25" wide
