State Faraday's laws of electromagnetic induction.

Expert Answer:

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.

Mathematically, begin mathsize 11px style straight epsilon equals negative dϕ over dt end style

Where ε = induced emf

       dΦ = small change in magnetic flux in small time dt.
