$A$ coil made of insulated copper wire is connected to a galvanometer. What will happen to the deflection of the galvanometer if this coil is moved towards a stationary bar magnet and then moved away from it? Give reason for your answer and name the phenomenon involved.
(N/A) When the coil is moved towards a stationary magnet,the magnetic flux linked with the coil changes,which induces an electric current in the coil. This causes the galvanometer to show a deflection in one direction.
When the coil is moved away from the magnet,the magnetic flux linked with the coil changes in the opposite sense,inducing a current in the opposite direction. This causes the galvanometer to show a deflection in the opposite direction.
The phenomenon involved is known as electromagnetic induction.
When the coil is moved away from the magnet,the magnetic flux linked with the coil changes in the opposite sense,inducing a current in the opposite direction. This causes the galvanometer to show a deflection in the opposite direction.
