2D cross sections of the magnetic field at y = 10 Mm. The streamlines show field lines, but their density does not signify the field strength. The field strength is shown by the color. (a) is the QS field right after the relaxation, (b) is the LFFF, (c) is the sum of the two proceeding, while (d) shows the EN right after the 20 min long ramp of the LFFF into the QS simulation.
