In electromagnetic induction, what is the source of electric energy that causes induced current?

Open in App

Solution

Electromagnetic induction is the phenomenon whereby changing the magnetic field, an alternating current is induced in a closed coil.
In this phenomenon, the kinetic energy of the magnet or the coil is converted into electrical energy.
The source of electric energy that causes induced current is the relative motion between the coil and the magnet.
Hence, the motion of the magnet is the source of electric energy that causes induced current.
