Question

explain why the direction of induced current in the coil of AC generator changes after every half revolution of the coil​

Answer 1

Answer:

Explanation:

After every half rotation, each side of the generator coil starts moving in the opposite direction.The side of the coil which was earlier moving downwards, after half rotation it starts moving upwards and is vice versa with the other generator coil.

Thus, due to change in the direction of the motion of the two sides of the coil in the magnetic field after every half rotation, so the induced current also changes direction.

Answer 2

Explanation:

After every half rotation, each side of the generator coil starts moving in the opposite direction. ... Thus, due to change in the direction of the motion of the two sides of the coil in the magnetic field after every half rotation, so the induced current also changes direction.
