Picture for the configuration of the current lines (full white lines) and adjoint current density (dashed white lines), which are symmetric to the horizontal line . The equipotentials are perpendicular to the current lines. The values of the dot product of are given in gray. The white areas have a negligible contribution to the integral and the very dark areas contribute strongly to the integral.
