Question

In a simple AC generator, how is the alternating current produced?
Options
A By rotating a loop in a constant magnetic field
Correct Answer
B By moving a magnet in and out of a coil
C By changing the resistance in the circuit
D By using a battery and a switch
Correct Answer

Option A is the correct answer.
