Turbulent (eddy) magnetic diffusivity over Coriolis number Co. The diffusivity is determined using an estimate of the turbulence in the simulations ηt = 1/3urms/kf (black) and using the cycle periods as in Eq. (12) (red) and Eq. (13) following Roberts & Stix (1972) (blue). The green dashed line indicates a power law fit of the black asterisk of Runs M4 to M15.
