Name 3 ways how the emf of an AC generator can be increased
1. Increasing the number of turns in the coil: By increasing the number of turns in the coil, the magnetic flux passing through the coil is also increased, resulting in a higher induced emf.
2. Increasing the strength of the magnets: By using stronger magnets, the magnetic field intensity is increased, leading to a higher induced emf in the coil.
3. Increasing the speed of rotation: By rotating the generator at a higher speed, the rate of change of magnetic flux through the coil is increased, resulting in a higher induced emf.
