Figure 21: The dependence of the time- and volume-averaged (a) Maxwell (green squares) and Reynolds stresses (orange diamonds) and (b) magnetic energy (blue circles) and in the turbulent state on the strength of the initial magnetic energy . Both the vertical and horizontal axes are normalized by the initial magnetic energy of the fiducial model . The initial field strength is varied from ~1011 to ~6  G. The dashed lines denote reference slopes proportional to (a) and (b) , respectively. We take the time-average of volume-averaged quantities during .
