In Fig. 29-53a, wire 1 consists of a circular arc and two radial lengths; it carries current il = 0.50 A in the direc)' __ ~. __ d~4-~d~~ ___ X 1 3 2 Fig. 29-51 24. Fig. 29-52 25. tion indicated. Wire 2, shown in cross section, is long, straight, and perpendicular to the plane of the figure. Its distance from the center of the arc is equal to the radius R of the arc, and it carries a current i2 that can be varied. The two currents set up a net magnetic field B at the center of the arc. Figure 29-53b gives the square of the field's magnitude B2 plotted versus the square of the current i~. The vertical scale is set by m = 10.0 X 1O-lO T2. What angle is sub tended by the arc?
