Question

how can we induce electric current?​

Answer 1

A changing magnetic field through a coil of wire therefore must induce an emf in the coil which in turn causes current to flow. The law describing induced emf is named after the British scientist Michael Faraday, but Faraday's Law should really be called Henry's Law. ... that determines the induced current.

Answer 2

HEY HERE IS YOUR ANSWER

A coil of wire with an electric current flowing through it becomes a magnet. Putting iron inside a current-carrying coil greatly increases the strength of the electromagnet. Changing magnetic fields induce electric currents in copper and other conductors....
