Physics:Elsasser number
From HandWiki
The Elsasser number, Λ, is a dimensionless number in magnetohydrodynamics that represents the ratio of magnetic forces to the Coriolis force.[1] [math]\displaystyle{ \Lambda = \frac{\sigma B^2}{\rho \Omega} }[/math]
where σ is the conductivity of the fluid, B is the magnetic field, ρ is the density of the fluid, and Ω is the rate of rotation of the body.
