(color online) Configurations of optimal y-gradient coil presented in Figs. 11(a) and 11(b) on the current-carrying surface, together with the corresponding distributions of electric potential. Panels (e) and (f) show the corresponding gradient field inaccuracy contours of panels (a) and (c) in yz section.
