Faraday in 1831 first discovered that whenever the number it of magnetic lines of forces in a circuit changes ,a emf is produced in the circuit and is known as induced emf and this phenomenon is known as Electro Magnetic Induction.If the circuit is closed one then a current flows through it which is known an induced current.This induced emf and current lasts only for the time while magnetic flux is chnaging.
