Step 1: Given data
Given that a coil made of insulated copper wire is connected to a galvanometer.
Step 2: Deflection of the galvanometer if this coil is moved towards a stationary bar magnet
The magnetic field that is associated with the coil will change when the coil moves towards a stationary magnet. So, the current will be induced in the coil. Due to this, the deflection of the galvanometer is shown in one direction.
Step 3: Reason for the deflection of the galvanometer if this coil is moved away from a stationary bar magnet
The magnetic field that is associated with the coil will get decreased when the coil moved away from a stationary magnet. So, the current that is induced in the coil will be in the opposite direction. Due to this, the deflection of the galvanometer is shown in the opposite direction.
Step 4: Explanation of the phenomenon involved
Electromagnetic induction is the phenomenon that shows what happens to the deflection of the galvanometer if this coil is moved towards a stationary bar magnet and then moved away from it when a coil made of insulated copper wire is connected to a galvanometer.
