Electromagnetic Induction — Important Questions

Generator

A generator works on electromagnetic induction to convert mechanical energy into electrical energy.

Opposite to the cause

Lenz's law states that the induced current opposes the change that produced it, ensuring conservation of energy.

Increases

According to Faraday's law, induced emf is proportional to the number of turns in the coil.

To transfer current without changing direction

Slip rings allow the transfer of current from the rotating coil to the external circuit while maintaining the alternating nature of the current.
