WebMaxwell’s Equations. Maxwell’s equations are the basic equations of electromagnetism which are a collection of Gauss’s law for electricity, Gauss’s law for magnetism, Faraday’s law of electromagnetic induction, and Ampere’s law for currents in conductors. Maxwell equations give a mathematical model for electric, optical, and radio technologies, like … WebElectrostatics. For electrostatic problems, Maxwell's equations simplify to this form: ∇ ⋅ D = ∇ ⋅ ( ε E) = ρ, ∇ × E = 0, where ε is the electrical permittivity of the material. Because the electric field E is the gradient of the electric potential V, E = − ∇ V., the first equation yields this PDE: − ∇ ⋅ ( ε ∇ V) = ρ.
