83. We refer to the center of the circle (where we are evaluating G B ) as C . Recalling the straight sections discussion in Sample Problem 29-1, we see that the current in the straight segments which are collinear with C do not contribute to the field there. Eq. 29-9 (with φ = π /2 rad) and the right-hand rule indicates that the currents in the two arcs contribute µµ 00 0 i R i R π2 bg −= to the field at C . Thus, the non-zero contributions come from those straight-segments which are not collinear with C . There are two of these “semi-infinite” segments, one a vertical distance
