Question 343: Electromagnetic Induction

Question

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 $$ 	imes \,{10^{ - 3}}$$ Wb.  The self-inductance of the solenoid is

Accepted Answer

Total flux linked with the solenoid, $$\phi $$ = N$$\phi $$
0
= 1000 $$ 	imes $$ 4 $$ 	imes $$ 10
-3
Wb = 4 Wb
$$ 	herefore $$  Self-inductance of solenoid
L = $${\phi  \over I} = {4 \over 4}$$ = 1 H

Answer

2 H

Answer

1 H

Answer

4 H

Answer

3 H

Electromagnetic Induction

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
