===== Description =====

Demonstrates magnetic breaking.    Classes Used: Phys 108





===== Purpose =====

1. To demonstrate eddy currents and electromagnetic damping.    2. To show how laminations reduce eddy current effects. 

===== Apparatus =====

Magnet, aluminum pendula 

===== Setup =====

Demonstrate that without the magnet, both "solid" and the "cut" pendula swing freely in much the same way. When swung between the poles of the magnet, however, the "solid" pendulum suffers a very strong damping force but this is not evident with the "cut" pendulum.
