Solution:

A generator is an electrical energy converter that converts mechanical energy into electrical energy. The electromagnetic induction principle governs the operation of an alternating current generator. An induced emf is created in a generator by rotating a coil in a magnetic field.

Electromagnetic Induction :
Electromagnetic induction occurs when a conductor is exposed to a fluctuating magnetic field and produces an electromotive force across the conductor. A conductor placed in a changing magnetic field causes a voltage to be produced across the conductor. This electromagnetic induction mechanism results in an electrical current.

Use :

The alternating current generator is used to generate alternating current with high transmission and generation power.
