Keyword: Induced Current

Demonstration Description:

A 9" coil with 120 turns is connected to a sensitive center-zero projection meter. A bar magnet is passed through the center of the coil, inducing a current which is shown on the meter. Reversing the poles or direction of the magnet will reverse the current. Passing the magnet through at different speeds will show different currents.
