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.


vA = B / (μo * ρ)1/2


vA = Alfven Speed,

B = Magnetic Flux Density,

μo = Permeability Of Free Space,

ρ = Plasma Mass Density
