Energy densities of the total magnetic field (left panel), and the azimuthally averaged fields (right) from Sets C (black dashed line) and G (black solid), from two sets of runs by Nelson et al. (2013; solid and dashed red lines) and from Hotta et al. (2016; blue solid lines). The red solid line consists of data from cases D3, D3a, and D3b of Nelson et al. (2013) with Pr_M = const. = 0.5. Correspondingly, the dashed red line shows data from cases D3, D3-pm1, and D3-pm2 of Nelson et al. (2013) with Pr_M varying from 0.5 to 2. From Hotta et al. (2016) we show data for cases “Low”, “Medium”, and “High”.
