Fig. 4From: The competition between Lorentz and Coriolis forces in planetary dynamosCalculated and predicted magnetic length scales. Magnetic length scale as a function of the Rayleigh number with Ekman and magnetic Prandtl numbers denoted by color. A best-fit between the calculated and predicted values is obtained when a pre-factor is included in (Eq. 10): ℓ B /D=1.3R m −1/2 (included here)Back to article page
