Figure a shows a wire that forms a rectangle (W = 20 cm, H = 30 cm) and has a resistance of 5.0m??). 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 z of the three fields with time t: the vertical axis scale is set by Bs = 4.0μT and Bb = -2.5B s and the horizontal axis scale are set by t s = 2.0 s. What are the

(a) Magnitude and

(b) Direction of the current induced in the wire?
