Question
The principle that moving a circuit in a magnetic field produces an EMF exactly like a battery is fundamental to the operation of which device?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Page 21 explicitly states: 'Thus moving a circuit in a magnetic field produces an emf exactly like a battery. This is the principle of an electric generator.'
Hint
Consider devices that convert mechanical energy (motion) into electrical energy.
