Figure (a) shows a wire that forms a rectangle (W = 16.0 cm, H = 34.0 cm) and has a resistance of 4.00 m?. Its interior is split into three equal areas, with magnetic fields $\vec{B_1}$, $\vec{B_2}$, and $\vec{B_3}$. 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 $B_5 = 6.00 \mu T$ and $B_b = -2.50B_5$. What are the (a) the magnitude and (b) direction of the current induced in the wire?
