MU0

MU0 = <Quantity 1.25663706e-06 N / A2>

Permeability of free space (SI).

\(\mu_0 = 4\pi \times 10^{-7}\) N A⁻², used here as an algebraic bridge to compute the magnetic field normalization FN_B and current density normalization FN_J in SI, which are then converted to the required CGS or SI output unit.

In Gaussian CGS, the Alfvénic magnetic normalization is \(B_0 = V_0\sqrt{4\pi\rho_0}\), which is numerically equivalent to the SI expression \(B_0 = V_0\sqrt{\mu_0\rho_0}\) when both results are expressed in Gauss.
