The Hall field via three vortices is studied and found to change its sign, depending of the relative strength of contributions via VF and VAF, similar to that of a system with two kinds of carriers. VZF is suggested to act as a domain wall between VF and VAF regions, accounting for the flux and antiflux regions observed in Nb films.13 pages, LaTex, no figureSuperconductivitytext
