In vacuum (microscopic formulation)

In vacuum, the relative permittivity is , so the vacuum permittivity determines the electric field. The same is true for the vacuum permeability and the magnetic field.

Notation

• is the electric field
• is the vacuum permittivity
• is the magnetic field
• is the vacuum permeability
• is the charge density
• is the current density
• is the nabla operator, so is divergence and is curl

Macroscopic formulation

Comments

• The equations shown here use the SI system of units. For the GCGS version, see Maxwell's equations in GCGS
• The connection between the integral and differential forms is given by Gauss's theorem and the Stokes theorem
