Contributions to the magnetic energy balance evaluated for sg-eta01 as a function of time. All values are normalised by the momentary magnetic energy density, E_mag. Shown in blue is the volume-averaged rate at which magnetic energy is converted to kinetic energy, ⟨v × B ⋅ J⟩. The values were calculated from the full three-dimensional output data using central differences every 10. The contribution arising from the Maxwell stress is shown as the black curve. Shown in red is the volumetric Ohmic dissipation rate, ⟨ − η|J|²⟩, also evaluated every 10 (see also Fig. 16). The time before tΩ₀ = 1000 corresponds to the ideal simulation, sg-mhd-2 (see also Löhnert & Peeters 2022). The resistive phase of sg-eta01 starts at tΩ₀ = 1000.
