Question 7 of 10 < Σ - / 1 !!! : View Policies Current Attempt in Progress A square wire loop with 2.1 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 8 = 21 V. If the magnitude of the field varies with time according to B = 0.035 -0.90 t, with Bin teslas and tin seconds, what are (a) the net emf in the circuit and (b) the direction of the (net) current around the loop? Ebat (a) i V (b)
