Answer:
Explanation:
This experiment is knows as Faraday's law of induction and as per this a coil is attached to a galvanometer and a magnet is moved near the coil.
As one pole of the magnet is pushed near the coil, the voltage increases and needle in galvanometer deflects. Same phenomena occurs while doing it from different pole , the needle get deflected in different direction.
This shows that the change in magnetic flux induce a electromotive force.
This force is same in quantity for both the poles but of opposite direction.
