Three‐dimensional structure of the stressed field lines of the evolving magnetic dipole in the case of CE1 at ﹩t=t_{S}﹩. The color code along the field lines visualizes the radial component of the current density, ﹩J_{R}﹩. The radial velocity of the erupting magnetic field is shown on a translucent plane cutting through the middle of the flux rope; the red (yellow) color corresponds to a flow velocity of the order of 1000 ﹩\mathrm{km}\,\,\mathrm{s}\,^{-1}﹩ (700 ﹩\mathrm{km}\,\,\mathrm{s}\,^{-1}﹩). The SB is shown as the yellow sphere. The flux rope in the case of CE2 looks qualitatively similar. This figure is also available as an mpeg animation.
