I amount of current is passed through a coil with N turns. Magnetic flux linked with the coil is ......

A

LI

B

NLI

C

`(NI)/L`

D

`N^2LI`

Text Solution

Verified by Experts

The correct Answer is:
B
Self induction of coil is `L=Phi/I`
where `Phi` = total magnetic flux linked with entire coil
I=current passing through the coil .
`therefore Phi=LI`
