A square wire loop with 1.5 m sides is perpendicular to a uniform magnetic field, with half the area of the loop in the field as shown in the figure. The loop contains an ideal battery with emf = 20 V. If the magnitude of the field varies with time according to B = 0.055 - 0.88 t, with B in teslas and t in seconds, what are(a) the net emf in the circuit and(b) the direction of the (net) current around the loop?
