In Figure (a), wire 1 consists of a circular arc and two radial lengths; it carries current i1 = 0.700 A in the direction 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 B⃗ at the center of the arc. Figure (b) gives the square of the field's magnitude B 2 plotted versus the square of the current i2 2 . The vertical scale is set by Bs 2 = 10.9 × 10-10 T 2 . What angle is subtended by the arc?

In Figure (a), wire 1 consists of a circular arc and two radial lengths; it carries current i1 = 0.760 A in the direction 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 (b) gives the square of the field's magnitude B2 plotted versus the square of the current i22. The vertical scale is set by Bs2 = 12.7×10−10 T2. What angle is subtended by the arc?
