A small circular loop of wire of radius a is located at the centre of a much larger circular wire loop of radius b. The two loops are in the same plane. The outer loop of radius b carries an alternating current `I=I_(0)cos(omegat)`. The emf induced in the smaller inner loop is nearly ?

A very small circular loop of radius a is initially (at t = 0) coplaner and concentric with a much larger fixed circular loop of radius b. A constant I flows in the larger loop. The smaller loop is rotated with a constant angular speed omega about the common diameter. The emf induced in the smaller loop as a function of time t is

Two different wire loops are concentric and lie in the same plane. The current in the outer loop (I) is clockwise and increases with time. The induced current in the inner loop
