Eddy Currents

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.
