Flux linked with each turn = 4 × 10-3 Wb ∴ Total flux linked = 1000[4 × 10-3] Wb φtotal = 4 ⇒ L i = 4 ⇒ L = 1 H

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 $4 \times 1 0^{- 3} Wb$ . The self-inductance of the solenoid is :

3 H

2 H

1 H

4 H

Flux linked with each turn $= 4 \times 1 0^{- 3} Wb$
$∴$ Total flux linked = $1000 [4 \times 1 0^{- 3}] Wb$
$ϕ_{t o t a l} = 4 \Rightarrow L i = 4 \Rightarrow L = 1 H$

Q. 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 4×10−3Wb. The self-inductance of the solenoid is :

3 H

2 H

1 H

4 H

Flux linked with each turn =4×10−3Wb ∴ Total flux linked = 1000[4×10−3]Wb ϕtotal​=4⇒Li=4⇒L=1H
