Solution: Answer is (c) same at all points
Magnetic field lines are parallel inside the solenoid. This indicates the existence of a strong magnetic field. As a result, the magnetic field is uniform throughout the solenoid.
The strength of the 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
(d) found to increase from one end to the other
(a) more at the ends than at the centre
(b) minimum in the middle
(c) same at all points
(d) found to increase from one end to the other
