*9 A square wire loop with 2.00 m sides is perpendicular to a uniform magnetic field, with half the area of the loop in the field as shown in Fig. 30-40. The loop contains an ideal bat- tery with emf 8 = 20.0 V. If the magnitude of the field varies with time according to B = 0.0420 – 0.870r, with B in tes- las and t in seconds, what are (a) the net emf in the cir- B bat Fig. 30-40 Problem 9.
