The energy and dissipation terms M , K , O , and V are outputs of our simulations and are plotted in Fig. S1 of the Supplementary materials. Generally, the magnetic energy and ohmic dissipation vary in phase, the kinetic energy and viscous dissipation vary in phase, and the kinetic and magnetic energy are out of phase. We compute M ˙ and K ˙ analytically after fitting a cubic B-spline function to time series of M and K. The work done by the Lorentz force, L, and the work done by the Buoyancy force, G, are obtained from Eqs. (2) and (3).
