HRW TP31-15P A square wire loop with 2.99 m sides is perpendicular to a uniform magnetic field, with half the area of the loop in the field as shown in Fig. 31-38. The loop contains a 20.0 V battery with negligible internal resistance. If the magnitude of the field varies with time according to B = 0.4110 0.780t, with B in teslas and t in seconds, what is the net emf in the circuit and the direction of the current though the battery? V counterclockwise O clockwise B 20.0 V Figure 31-38
