Chapter 8.2, Problem 2cT
Electric generator
Remove the battery and ammeter from circuit in part B and insert micro-ammeter as shown.
1. Suppose that the coil is made to spin by an external agent such as yourself.
Predict the deflection of the micro-ammeter needle throughout a complete revolution of the coil.
How would your prediction change if:
•the coil were made to rotate the other way?
•the poles of the magnet were reversed?
2. Check your predictions by gently rotating the coil so that it spins for a little time on its own before coming to a stop.
When the coil of the apparatus above is made to spin by an external agent, the apparatus is called an electric generator.
