Elsasser number - Misplaced Pages

The Elsasser number, Λ, is a dimensionless number in magnetohydrodynamics that represents the ratio of magnetic forces to the Coriolis force.

$\Lambda ={\frac {\sigma B^{2}}{\rho \Omega }}$

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.
