Physics for IGCSE & O level - Magnets And Currents (Section 1 - No. 41)
What happens to the direction of the current in a generator as the coil rotates?
The direction remains constant.
The direction reverses periodically.
The direction becomes random.
The direction decreases.
Explanation
As the coil rotates, the current direction reverses periodically in an AC generator due to the changing interaction with the magnetic field.
