Shows a square frame of wire having a total resistance r placed coplanarly with a long, straight wire. The wire carries a current I given by i= i_0 sin omega t . Find(a) the flux of the magnetic field through the square frame, (b) the emf induced in the frame and (c) the heat developd in the frame in the time interval 0 to (20pi)/(omega) .
