AC Generator

The video explains how electromagnetic induction is used in AC generators. It describes the structure of an AC generator, which includes a coil that rotates within a magnetic field. The video details the working principle, showing how the coil's movement induces an electromotive force (emf) and generates alternating current. It also explains the direction of current flow and how it changes with the coil's rotation, completing a cycle every 360 degrees.

What is the principle behind the operation of an AC generator?

Describe the role of the coil in an AC generator.

Explain how the orientation of the coil affects the induced emf.

What happens to the direction of the induced current as the coil rotates?

How does the sine function relate to the induced emf in an AC generator?
