vacuum magnetic permeability ( μ0 )

  • Name: vacuum magnetic permeability
  • Symbol: μ0
  • Value: 1.2566370621219×10−6
  • Dimension: N/A2

The magnetic constant, denoted μ0, is the magnetic permeability in a classical vacuum. Vacuum permeability is derived from production of a magnetic field by an electric current or by a moving electric charge and in all other formulas for magnetic-field production in a vacuum.
