Self-Inductance & Energy

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

Show answer and solution

Answer: (b)

$L = \frac{N\phi}{I}$
$L = \frac{1000 \times 4\times10^{-3}}{4}$
$L = 1\text{ H}$ , so the answer is (b).
