The magnetic field lines in space around the magnet caused by the bar magnet pass through the coil. As the amount of magnetic flux through the coil changes, because of the movement of the coil, electric current is induced in the coil turns. This is indicated by the deflection of the galvanometer needle.
When the coil moves nearer to the magnet the deflection shows in one direction. When the coil moves away from the magnet the deflection shows the other way from the middle 0, as the direction of the current in the coil reverses.
