The magnetic field inside a tightly wound, long solenoid is ` B= (mu_0)ni`. It suggests that the field does not depend on the total length of the solenoid, and hence if we add more loops at the ends of a solenoid the field should not increase. Explain qualitatively why the extra added loops do not have a considerable effect on the field inside the solenoid.
