NEET Physics Mutual Inductance MCQ Question
Type: MCQ-numerical-Medium-Class 12
Two coils are placed near each other. When the current in one coil is changed at the rate of 5 A/s, an emf of 2 mV is induced in the other. The mutual inductance of the two coils is
A
0.4 mH
B
5 mH
C
10 mH
D
5 H
Correct Answer
Option A
Detailed Explanation
The mutual inductance M is calculated using the formula emf = M (di/dt). Substituting the given values gives M = 0.4 mH.
