The toroidal field, B_T(x, y), produced by the vertical currents, J_z(x, y, 0), derived from (a) the SHARP photospheric vector magnetogram, (b) the lower boundary data of the CFIT N solution, and (c) the lower boundary data of the CFIT P solution for AR 11429 on 2012 March 6 23:36 UT. The background color map in each panel shows J_z(x, y), the black contours show the main PILs corresponding to B_z(x, y) = 0, and the orange vectors show B_T(x, y).
