RMS toroidal and poloidal axisymmetric magnetic fields (top), and RMS magnetic dipole (bottom) compensated with the measured shear rate as a function of the ratio between the effective Brunt-Väisälä frequency to the rotation rate at the outer sphere N_eff/Ω_o. The magnetic field is rendered dimensionless and compensated for the effect of the shear using Eqs. (17) and (18). Dotted lines show the best fits of the data with Fuller’s theoretical scaling laws (Eqs. (15) and (16)) within a multiplying factor. Filled and empty markers represent self-sustained and transient dynamos, respectively.
