Question

In Fig.Q2 below, a circular loop of radius a = 10 cm is located within a (spatially) uniform magnetic field H=H₂ cos(2лft) pointing into the paper, where Ho = 10 mA/m, B = μH,Ho = 4 x 107 Hm¹ and f= 100 MHz. Find the amplitude of the induced emf around the loop. Determine the direction (clockwise or anti-clockwise) of the induced emf/current at time t slightly after t = 0.
