What is induced emf ?
Asked by Topperlearning User | 07 Jul, 2015, 09:56: AM
Faraday observed that, whenever the amount of magnetic flux linked with a conductor changes, an emf is induced and it lasts as long as the magnetic flux through the conductor changes. The magnitude of the induced emf is directly proportional to rate of change of the magnetic flux.
If
represents the change in flux in time t, therefore,
