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
- R1/R2
- R2/R1
- \(\mathrm{R}_{1}^{2} / \mathrm{R}_{2}\)
- \(\mathrm{R}_{2}^{2} / \mathrm{R}_{1}\)
Answer
(D) R _ 2 ^ 2 / R _ 1
