Main Question or Discussion Point

What will happen when I push a magnets into a solenoid with constant speed throughout? I understand that when the magnet leaves and enters an induced emf will occur, but in the middle no emf will occur. Why is this so? I thought that the magnetic flux linkage changes as it moves in the solenoid?

As the magnet moves through the solenoid with both the pole inside, for each loop of the coil with increasing flux linkage, there is a loop with a decreasing flux equally, hence their emfs cancel each other out ( the solenoid is a combination of the loops in series).
