(a,b) Magnetic energy in the first six axisymmetric spherical harmonics (m = 0) as a function of spherical radius r at N_ρ = 6, $\stackrel{\sim }{\mathit{Ra}}=32$. (a) High-energy state, anti-solar rotation, t_rot ≈ 6900. (b) Low-energy state, three-layer rotation, t_rot ≈ 7300. The relative buildup in dipolarity with respect to large scales takes place only during low-energy states with weakened three-layer rotation. (c) The energy in axisymmetric dipole normalized with the total large-scale magnetic energy up to 7th spherical harmonic, ∑E_{l, m ≤ 7}, at $\stackrel{\sim }{\mathit{Ra}}=32$. The modal energy was averaged over dipolar intervals for N_ρ = 4, 6, and over the whole time evolution for N_ρ = 2.
