JEE Main 2022Electromagnetic Induction Question with Solution

JEE Main 2022 (26 Jun Shift 2)

Question

Two coils of self inductance L1 and L2 are connected in series combination having mutual inductance of the coils as M. The equivalent self inductance of the combination will be

Show full solutionCorrect option: B
Correct answer
BL1+L2-2M

Step-by-step explanation

Here self inductances are in series but their mutual inductances are linked oppositely.

As the inductors connected are in series opposition, hence magnetic flux will be opposing each other. Therefore,

Leq=L1+L2-2M
