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.
