Elsasser number

The Elsasser number, Λ, is a dimensionless number in magnetohydrodynamics that represents the ratio of magnetic forces to the Coriolis force.[1]

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.

gollark: Manufacturers tend to limit authorized technician stuff a lot and/or overcharge massively.
gollark: Okay? I'd like to be able to, and I'd like it to be possible without expensive specialized equipment.
gollark: Also, Linux on DeX is... cancelled or something.

gollark: Hmm, good idea.
