Two conducting circular loops of radii $R_1$ and $R_2$ are placed in the same plane with their centre coinciding. If $R_1 >> R_2$ the mutual inductance $M$ between them will be directly proportional to

  • A

    $\frac{{{R_1}}}{{{R_2}}}$

  • B

    $\frac{{{R_2}}}{{{R_1}}}$

  • C

    $\frac{{{R_1^2}}}{{{R_2}}}$

  • D

    $\frac{{{R_2^2}}}{{{R_1}}}$
