Top row: spatial distribution of the plasma density for (a) the semi-equilibrium stage. Panels b–d show the different MFR eruption stages, where the overplotted solid curves represent the MFLs projected in the x − y plane. Middle row: same as in the top panel for temperature. Bottom row: distribution of the LF over the entire simulation domain, where the overplotted arrows represent the LF direction in the x − y plane. The saturation level of the color bar is taken up to 10⁻⁵ G² cm⁻¹ for a better visualization of the enhanced LF regions. Animations of the figures are available online (the height and width aspect ratio of the figures are not to scale).
