The loop is in a magnetic field 0.20 t whose direction is perpendicular to the plane of the loop. at t = 0, the loop has area a = 0.285 square m. suppose the radius of the elastic loop increases at a constant rate, dr/dt = 3.70 cm/s .a) determine the emf induced in the loop at t = 0.b)determine the emf induced in the loop at t = 1.00 s .
