Relaxation of Fields, Skin Depth

This article discusses the relaxation of electric fields and charge in conducting media.

The quasistatic assumption allows us to neglect the contribution of
∂B t to E , which simplifies the problem.

The three equations that govern the relaxation process are:

• The conservation-of-charge relation: ∇ ρ = 0
• Gauss’s law: ∇ • D = ρ
• Ohm’s law: J = σE
