Time evolution of the magnetic and turbulent kinetic energy densities for model Standard with B_o = 1.5 × 10¹⁴ G. The black and blue lines are the toroidal and poloidal contributions of the magnetic energy density, and the red line is the turbulent kinetic energy density (i.e., the energy of the nonaxisymmetric component of the velocity). The magenta line is the axisymmetric contribution to the toroidal magnetic energy density.
