Hint: Electromagnetic induction is the process of production of the voltage or the current in a conductor by a changing magnetic flux. It is also known as magnetic induction.

Complete step by step answer:
Electromagnetic induction is defined as the induction of an electromotive force by the motion of a conductor across a magnetic field or by the change in the magnetic field. Electromagnetic induction happens when a conductor is set in a moving magnetic field by using an AC power source or when the conductor is always moving In a stationary magnetic field.

When the conductor cuts the magnetic field lines, Electromagnetic induction occurs and the magnetic force on a charge depends on the velocity and the magnetic field it moves through. This force will be perpendicular to both the magnetic field and the direction of motion of the conductor.

When a circuit with an alternating current flowing through generates current in another circuit that was placed nearby, Electromagnetic induction occurs.

The basic principle of electromagnetic induction is that the changing magnetic field in the region of the space produces an electric field that is perpendicular to it. Thus when the magnetic field changes in the region of space, generates an electric field and due to this, the electric currents can flow in the closed circuits when the magnetic flux changes through it.

Note: In general the current produced by Electromagnetic induction will be greater when the magnet or when the coil moves fastly or if the coil has more number of turns or when the magnet is stronger.
