PURPOSE: Demonstrate the enormous magnitude of induced voltage in many circumstances.

DESCRIPTION: A 9-volt battery is connected across a large inductor, which in turn is then disconnected from the battery and immediately connected across a fluorescent light. Collapse of the magnetic field in the transformer induces a voltage large enough to cause the fluorescent bulb to flash - well over 100 volts, or over ten times the voltage of the battery.

SUGGESTIONS:

EQUIPMENT: Transformer, battery, fluorescnt lamp, and switch system mounted for use. Can be connected to an oscilloscope to view the induced voltage if requested.

SETUP TIME: None.
