A small coil is connected to a galvanometer G, as shown. When a magnet is allowed to fall towards the coil, the galvanometer pointer gives a momentary deflection to the right of the zero position. The magnet moves through the coil. What happens to the galvanometer pointer as the magnet falls away from the coil?
