Faraday's Law
Faraday's laws of electromagnetic induction state:
i) An induced e.m.f is setup when the magnetic field linking that circuit changes
ii) The magnitude of the induced e.m.f in any circuit is proportional to the rate of alter of the magnetic flux linking the circuit.
Self Inductance If a current is passed through a coil, it creates a flux within the coil. Any attempt to change this flux will create a back emf that acts to oppose the chang
