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.

 

Magnetic Flux Density:
Permeability Of Free Space:
Plasma Mass Density:

 

 

 

Alfven Speed: m/s

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
