FN_B

FN_B = <Quantity 2.2068914 G>

Magnetic field normalization for MAS, in Gauss.

The code B field is normalized so that the Alfvén speed equals the reference velocity FN_V when \(B_\text{code} = 1\):

\[B_0 = V_0\sqrt{\mu_0\,\rho_0} \approx 2.2\;\text{G}.\]

This is on the order of typical large-scale coronal magnetic field strengths.
