PURPOSE: To demonstrate magnetic induction with 110 VAC.
DESCRIPTION: Closing the switch puts 110 VAC on the primary coil, which is coupled to the secondary coil (on top) by a ferromagnetic core. The induced current in the secondary coil lights the 110 VAC light bulb.
SUGGESTIONS: For safety, the ground fault protection device is used with thius demonstration.
REFERENCES: (PIRA 5K30.20)
EQUIPMENT: Induction coil with light bulb load.
SETUP TIME: None.
