Question

1.	The strength of magnetic field inside a long current carrying straight solenoid is
(a)	more at the ends than at the centre
(b)	minimum in the middle
(c)	same at all points
found to increase from one end to the other

Soln:

Answer is (c) same at all points
Explanation:
Inside the solenoid magnetic field lines are straight. This indicates strong magnetic field. Hence magnetic field is uniform at all points inside the solenoid.
