N_{m p}

Definition

quotient of gas pressure and magnetic pressure in a gas or plasma, expressed by

$N_{m p} = p \frac{2 μ}{B^{2}}$ ; where

$p$ :: is pressure (ISO 80000-4: Mechanics),

$μ$ :: is magnetic permeability (IEC 80000-6: Electromagnetism), and

$B$ :: is magnetic flux density (IEC 80000-6: Electromagnetism)

quotient de la pression d'un gaz par la pression magnétique dans un gaz ou un plasma, exprimé par

$N_{m p} = p (2 μ) / B^{2}$ ; où

$p$ :: est la pression (ISO 80000-4: Mechanics),

$μ$ :: est la perméabilité magnétique (IEC 80000-6: Electromagnetism), et

$B$ :: est l'induction magnétique (IEC 80000-6: Electromagnetism)

Notes

The quantity $p_{m} = B^{2} / (2 μ)$ is called magnetic pressure, where

$B$ :: is magnetic flux density (IEC 80000-6: Electromagnetism), and

$μ$ :: is magnetic permeability (IEC 80000-6: Electromagnetism).

La grandeur $p_{m} = B^{2} / (2 μ)$ est appelée pression magnétique, où

$B$ :: est l'induction magnétique (IEC 80000-6: Electromagnetism), et

$μ$ :: est la perméabilité magnétique (IEC 80000-6: Electromagnetism).
