Consider a circular conducting loop of radius 'a'. Concentric and coplanar to it is a circle of radius 'b' (b<a) within which there is uniform magnetic field perpendicular to the plane of the conducting loop. The magnetic field is varying at a rate dB/dt.
QUESTION: Does the induced emf in the loop depend on the radius 'a'? If not, then can the radius 'a' take larger values without limit?
