Figure (a) shows a wire that forms a rectangle (W = 20.0 cm, H = 27.0 cm) and has a resistance of 7.00 m2. Its interior is split into three equal areas, with magnetic fields B1, B2, and B3. The fields are uniform within each region and directly out of or into the page as indicated. Figure (b) gives the change in the z components B, of the three fields with time t; the vertical axis scale is set by Bg = 3.50 µT and Bp = -2.50B5. What are the (a) the magnitude and (b) direction of the current induced in the wire?
