A long solenoid has 500 turns. When a current of 2 ampere is passed through it, the resulting magnetic flux linked with each turn of the solenoid is Wb. The self-inductance of the solenoid is
Multiple Choice Options
- A 1.0 henry
- B 4.0 henry
- C 2.5 henry
- D 2.0 henry
Step-by-Step Verified Solution
Total number of turns in the solenoid,
N = 500 Current, I = 2A.
Magnetic flux linked with each turn = 4 _ 10 �3 Wb
Self inductance of coil :
L = N _ I = 500 _ 4 _ 10 3 2 = 1 H
