A long solenoid has `1000` turns. When a current of `4A` flows through it, the magnetic flux linked with each turn of the solenoid is `4xx10^(-3)Wb`. The self-inductance of the solenoid is

A

4 H

B

3 H

C

2 H

D

1 H

Text Solution

Verified by Experts

The correct Answer is:
D
Number of turn = 1000
Net magnetic flux = `N phi = 4 xx 10^(-3) xx 10^3`
`= 4 Wb`
`phi = LI`
`4 = L xx 4 `
` L = 1H`
