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:
1. | \(\dfrac{R_1}{R_2}\) | 2. | \(\dfrac{R_2}{R_1}\) |
3. | \(\dfrac{R^2_1}{R_2}\) | 4. | \(\dfrac{R^2_2}{R_1}\) |
