WebThe divergence of the electric field is equal to charge density over epsilon (Permittivity constant). Div (E) = p/e, ok, and yes, if you have a single positive charge, the divergence is nonzero only where the charge is located. In the rest of the space, the divergence is zero. Up to this point, everything is fine. WebTo show that the given equation for vector H satisfies Maxwell's equations, we need to use the following two equations from Maxwell's equations: ∇ → × E → = − d B d t (Faraday's Law of electromagnetic induction) ∇ → × H → = d B d t + J (Ampere's Law with Maxwell's correction) where E is the electric field, H is the magnetic ...
