Purpose: Demonstrate the magnitude of induced voltage
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.
