Question 10
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
(d) found to increase from one end to the other

Answer 1

Option (c) is correct.
The magnetic field is the same at all points inside the long solenoid. The magnetic field inside a long straight current - carrying solenoid is uniform which is represented by parallel lines.
