NEET 2021 Physics Mutual Inductance MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Two conducting circular loops of radii R₁ and R₂ are placed in the same plane with their centres coinciding. If R₁ >> R₂, the mutual inductance M between them will be directly proportional to :
A
R₁/R₂
B
R₂/R₁
C
R₁²/R₂
D
R₂²/R₁
Correct Answer
Option D
Detailed Explanation
For two loops with R₁ >> R₂, the mutual inductance is proportional to the area of the smaller loop, hence M ∝ R₂²/R₁.
