First law: Whenever the amount of magnetic flux linked with the circuit changes, an emf is induced in the circuit. The induced emf lasts so long as the change in the magnetic flux continues.
Second law: The magnitude of emf induced in the circuit is directly proportional to the rate of change of magnetic flux linked with the circuit.
Where ε = induced emf
dΦ = small change in magnetic flux in small time dt.
