What is Faraday’s law of induction?

A current is induced in the coil, in case a current is switched on or off in the solenoid coil. This induction is also observed when the current in the solenoid coil is increased or decreased. Current is induced in the coil when it is moved aside from the front of the solenoid. From these experiments, it is understood that whenever the number of magnetic lines of force passing through the coil changes, current is induced in the coil. This is known as Faraday’s law of induction. The current produced in the coil is called the induced current.
