The diagram shows a coil connected to a centre zero galvanometer G the galvanometer shows a deflection to the right when the N - Pole of a powerful magnet is moved the the right as shown:
State the observation in G when, both the coil and the magent, are moved to the right at the same speed.
Zero deflection will be seen in the Galvanometer
When both the coil and the magnet, are moved to the right at the same speed there is no change in magnetic flux linked with the coil and hence there is no emf induced in the coil. Hence Galvanometer shows no deflection.
