Find the self-inductance of an N-turn toroidal coil similar to the one shown in Fig. 5.39 (page 238) except that the cross section is a square with one of its diagonals parallel to the z-axis. More specifically, the square whose vertices are (b + a,0,0), (b,0, a), (b – a, 0, 0) and (b,0, -a) is one of the intersections of the coil with the rz coordinate plane. The parameters a and b satisfy b > a > 0. r' = (s' cos o', s' sin o', z'). %3| г ךוורור ווmmm リル r" г FIGURE 5.39
