Magnetic energy e_M normalized by time-averaged turbulent kinetic energy ﹩\bar{{e}_{{\rm{K}}}^{{\prime} }}﹩ for grid sizes (a) 512³, (b) 1024³, and (c) 2048³  zones. See the legends for Pm and saturation energy e_s from an average over the final 2.5% of simulation time. Markers are shown at the time of SN explosions. Note that the timescales are dramatically smaller at higher resolution.
