AIPMT PRELIMS 2006 Physics Mutual Inductance MCQ Question

Type: MCQ-numerical-Medium-Class 12

Two coils of self-inductances 2 mH and 8 mH are placed so close together that the effective flux in one coil is completely linked with the other. The mutual inductance between these coils is :

A

8 mH

B

12 mH

C

4 mH

D

16 mH

Correct Answer

Option C

Detailed Explanation

The mutual inductance M is given by the geometric mean of the self-inductances, M = √(L₁L₂) = √(2 mH * 8 mH) = 4 mH.
