AC Generator
An AC generator produces electrical energy from mechanical work, just the opposite of what a motor does. In it, a shaft is rotated by some mechanical means, such as an engine or a turbine starts working and an emf is induced in the coil.
It is based on the phenomenon of electromagnetic induction which states that whenever magnetic flux linked with a conductor (or coil) changes, an emf is induced in the coil.
Which method is used to induce an emf or current in a loop in AC generator?
Options:
(a) A change in the loop's orientation
(b) A change in its effective area
(c) Both ( a) and ( b)
(d) Neither ( a) nor ( b)
