Two conducting circular loops of radii \(R_1\) and \(R_2\) are placed in the same plane with their centres coinciding. If \(R_1>R_2\), the mutual inductance \(M\) between them will be directly proportional to
- A \(\frac{\mathrm{R}_1}{\mathrm{R}_2}\)
- B \(\frac{\mathrm{R}_2}{\mathrm{R}_1}\)
- C \(\frac{\mathrm{R}_1^2}{\mathrm{R}_2}\)
- D \(\frac{\mathrm{R}_2^2}{\mathrm{R}_1}\)
Answer & Solution
Correct Answer
(D) \(\frac{\mathrm{R}_2^2}{\mathrm{R}_1}\)
Step-by-step Solution
Detailed explanation
\(M = \frac{\mu_0 \pi R_2^2}{2 R_1}\) \(M \propto \frac{R_2^2}{R_1}\)
