where

B is the magnetic flux density

μ0 is the magnetic constant

Note 1 to entry: The total pressure on a given flow of conducting fluid, which is the sum of the mechanical pressure, the magnetic pressure and the hydrostatic pressure, is a constant for this flow of conducting fluid.

Note 2 to entry: The coherent SI unit of magnetic pressure is newton per square metre, N/m2.

B est l'induction magnétique

μ0 est la constante magnétique

Note 1 à l’article: La pression totale sur un écoulement donné de fluide conducteur, soit la somme de la pression mécanique, de la pression magnétique et de la pression hydrostatique, est une constante pour ledit écoulement de fluide conducteur.

Note 2 à l’article: L’unité SI cohérente de pression magnétique est le newton par mètre carré, N/m2.
