Figure (a) shows a wire that forms a rectangle (W=21.0 cm, H = 34.0 cm) and has a resistance of 7.00 m2. Its interior is split into thre 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 B₂ of the three fields with time t; the vertical axis scale is set by B = 3.50 μT and Bb= -2.50B,. What are the (a) the magnitude and (b) direction of the current induced in the wire? H B₁ ● B₂ (a) B₂ -By t(s) (b)
