A coil having n turns and resistance R . is connected with a galvanometer of resistance 4R . This combination is moved in time t seconds from a magnetic field W1 weber to W2 weber. The induced current in the circuit is
As we learnt in
Induced current
Change in flux =
For N turns -
- wherein
N= Number of turns in the Coil
Negative sign shows that induced emf change the flux.
Total current per coil
Induced current is oppoiste to its cause of production
