  1. The Rayleigh number is Ra, the Ekman number is E and the magnetic Prandtl number is Pm. For all models we set the Prandtl number as \(Pr=1\). The magnetic Reynolds number Rm is calculated based on the total kinetic energy in the shell, \(r_{\text {e}}\) denotes the radial level at which the simulations were analyzed, and \(\bar{\delta \tau }\) denotes the average time difference between successive snapshots in units of magnetic advection time
