This is the process by which electricity is produed in something placed in a changing magnetic field.
There are two laws:
1. Faradays law- this states that the induced EMF is proportional to the rate of change of magnetic flux linked withthe circuit.
EMF isproportioal to fie/t
fie=BA
This is therefore to do with the size of the EMF.
2. Lenz's law- is to do with the direction of EMF. The law states that the emf is such to oppose the change producing it. Combiningthe laws.
EMF=-Nxfie/t
