A long solenoid has . When a current of flows through it, the magnetic flux linked with each turn of the solenoid is . What is the self-inductance of the solenoid?
Step 1: GIven data
A long solenoid has
Step 2: Formula used
This formula belongs to the self-inductance of the solenoid.
Here, =magnetic flux
Step 3: Calculating self-inductance
So, we have flux linked with each turn
Total flux linked =
Now, on the basis of the formula
Now on putting the values
Hence, the self-inductance of the solenoid is .
