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

$l$ :: is characteristic length (ISO 80000-3: Space and time),

$σ$ :: is electrical conductivity (IEC 80000-6: Electromagnetism),

$η$ :: is dynamic viscosity (ISO 80000-4: Mechanics), and

$v$ :: is speed (ISO 80000-3: Space and time)
