Question

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 pointsNOTE: In my opinion, it should be (b) part but inmeritnation answer it is given as (d) because the magnetic lines curve at the poles to make a closed loop making the lines not parallel...........

Answer 1

Answer:

Option d

Explanation:

Inside a long straight solenoid, the current carried by the magnetic field is same or uniform throughout. This phenomenon is because , they have lines which are parallel in nature.

Hence current conducted by the parallel lines are uniform.

But at the end, lines get apart and the current conducted by the magnetic field is no more uniform.

A solenoid is a wire which is coiled and helical in nature and is tightly wound.
