Definition

quotient of Joule heating energy and magnetic field energy in a plasma, expressed by

$J o_{m} = 2 ρ μ c_{p} Δ T / B^{2}$ ; where

$ρ$ :: is mass density (ISO 80000-4: Mechanics),

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

$c_{p}$ :: is specific heat capacity at constant pressure (ISO 80000-5: Thermodynamics),

$T$ :: is thermodynamic temperature (ISO 80000-5: Thermodynamics), and

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