Solution
The correct option is A Electromagnetic induction Electromagnetic induction is the phenomenon of producing an emf in a circuit whenever there is a change in magnetic flux linked with the coil. Lenz's law states that if the magnetic flux linked with the coil changes, an emf is induced in the coil in such a way so as to oppose that change in magnetic flux.
