62. Using Eq. 29-26, we find that the net y -component field is 22 01 02 3 / 2 3 / 2 12 , 2( ) ) y iR B Rz µµ ππ =− ++ where z 1 2 = L 2 (see Fig. 29-76(a)) and z 2 2 = y 2 (because the central axis here is denoted y instead of z ). The fact that there is a minus sign between the two terms, above, is due to the observation that the datum in Fig. 29-76(b) corresponding to B y = 0 would be impossible without it (physically, this means that one of the currents is clockwise and the
