Magnetic energy. Left panel: out-of-plane magnetic energy component (solid lines, values on the left axis) and the in-plane magnetic energy (dotted lines, values on the right axis), as a function of height at several time moments. The values are averaged in horizontal direction. Right panel: time evolution of the spatially averaged in-plane magnetic energy (green solid line), out-of-plane magnetic energy (orange solid line), and the sum of the kinetic energies of charges and neutrals (red line), taken with respect to t = 0 values. Green dotted and orange dotted lines show the force working against the Lorentz force by the in-plane and out-of-plane magnetic field components, correspondingly.
