Question 3
Choose the correct option.
The magnetic field inside a long straight solenoid-carrying current
(a) is zero
(b) decreases as we move towards its end
(c) increases as we move towards its end
(d) is the same at all points

Answer 1

Correct Option: (d)
The magnetic field inside a long straight current-carrying solenoid is uniform which is represented by parallel lines. Hence, the magnetic field inside a long straight solenoid carrying current is the same at all points.
