એક લાંબા સોલેનોઇડના આંટાની સંખ્યા \(1000 \) છે. જયારે તેમાંથી \(4\;A\) નો પ્રવાહ વહેતો હોય, ત્યારે સોલેનોઇડના દરેક આંટા સાથે સંકળાયેલ ફ્‍લકસ \(4 \times10^{-3} \;Wb\) છે. આ સોલેનોઇડનું આત્મપ્રેરકત્વ ....... \(H\) હશે?

A \(3\)
B \(2\)
C \(1\)
D \(4\)

Verified Solution

Answer & Solution

Correct Answer

(C) \(1\)

Step-by-step Solution

Detailed explanation

\(\text { Here, } N=1000, I=4\, \mathrm{A}, \phi_{0}=4 \times 10^{-3}\, \mathrm{Wb}\) Total flux linked with the solenoid, \(\phi=N \phi_{0}\)

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
