Snapshots of the radial magnetic field B_r at R = 1 R_⊙ in the COCONUT model (lower radial boundary corresponding to the base of the solar corona). Left panel: magnetic field produced by the initial relaxation run for the maximum activity solar wind. Right panel: same location after the insertion of the flux rope. The insertion of the flux rope results in the addition of two polarities and a modification of the near photospheric field. The blue arrow indicates the negative polarity, while the red one indicates the positive polarity. The magnetic inversion line is demarcated by the dotted line.
