Faraday’s law of electromagnetic induction:
- Whenever there is a change in magnetic flux linked with a coil, an emf is induced, which lasts as long as the change inmagnetic flux is linked with the coil changes.
- The magnitude of the induced emf is directly proportional to the rate of change magnitude flux linked with the coil.
LED lamps are more energy-efficient as they consume significantly less power and last longer compared to incandescent lamps.
