defence exam Army Havildar SAC Mock Test Series 2025 Physics Electromagnetic Induction and Inductance Self-Induction
Two conducting circular loops A and B are placed in the same plane with their centres coinciding as shown in figure. The mutual inductance between them is:
1
\(\rm \frac{\mu_0\pi a^2}{2b}\)
2
\(\rm \frac{\mu_0}{2\pi}.\frac{b^2}{a}\)
3
\(\rm \frac{\mu_0\pi b^2}{2a}\)
4
\(\rm \frac{\mu_0}{2\pi}.\frac{a^2}{b}\)
