Calculate Alfven Velocity



The calculator will calculate the Alfven Speed for given values of magnetic flux density, permeability of free space and plasma mass density. The Alfven wave in a plasma is a low-frequency travelling oscillation of the ions and the magnetic field. The ion mass density provides the inertia and the magnetic field line tension provides the restoring force.
Formula: vA = B / (μo * ρ)1/2
Where, vA = Alfven Speed, B = Magnetic Flux Density, μo = Permeability Of Free Space, ρ = Plasma Mass Density
