हिन्दीA long solenoid has 1000 turns. When a current of \( 4\text{ A} \) flows through it, the magnetic flux linked with each turn of the solenoid is \( 4 \times 10^{-3}\text{ Wb} \). The self-inductance of the solenoid is
Correct answer · Option 2
\( 1\text{ H} \)
Explanation
Total flux linkage \( N\Phi = L I \implies 1000 \times (4 \times 10^{-3}) = L \times 4 \implies 4 = 4L \implies L = 1\text{ H} \).
