Electromagnetic induction or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field.

In electrical engineering, two conductors are said to be inductively coupled or magnetically coupled when they are configured in a way such that change in current through one wire induces a voltage ac
Example of inductive coupling, 1910. The bottom coil is connected to AC power. The alternating magnetic field through the top coil induces current in it which lights the lamp.
