Calculate Alfvén velocity for magnetohydrodynamic waves in plasmas

📐 Alfvén Velocity Formulas

v_A = B / √(μ₀ × ρ)
v_A = B / √(4π × ρ) (CGS units)
ω = k × v_A (dispersion relation)
v_A = Alfvén velocity, B = magnetic field, μ₀ = permeability, ρ = density, ω = frequency, k = wavenumber

💡 Tips & Information

  • Alfvén velocity is independent of wavelength
  • Higher magnetic field = faster Alfvén waves
  • Lower density = faster wave propagation
  • Alfvén waves are transverse waves
  • Important for plasma confinement and fusion
