In This post you will get answer of Q.
A long solenoid has $1000$ turns. When a current of $4,A$ flows through it, the magnetic flux linked with each turn of the solenoid is $4 times 10^{-3} , Wb$. The self-inductance of the solenoid is :

Solution:

Flux linked with each turn $= 4 times 10^{-3} , Wb$

$therefore$ Total flux linked = $ 1000[4 times 10^{-3}] Wb$

$phi_{total} = 4 , Rightarrow , L , i = 4 , Rightarrow , L = 1 H $
