A small coil of radius r is placed at the centre of a large coil of radius R , where R gtgt r . The two coils are coplanar. The mutual inductance between the coils is proportional to

A small coil of radius r is placed at the center of a large coil of radius R, where R>>r. The two coils are coplanar. The mutual inductance between the coils is proportional to

A small coil of radius r is placed at the centre of a large coil of radius R , where R gtgt r . The two coils are coplanar. The mutual inductance between the coils is proportional to

(A): When number of turns in a coil doubled, coefficient of self inductance of the coil becomes four times. (R): Coefficient of self inductance is proportional to the square of number of turns.
