WebThe electric field of a point charge at the origin is given by \begin{gather*} \EE = \frac{1}{4\pi\epsilon_0} \frac{q\,\rhat}{r^2} \end{gather*} We can take the divergence of … WebThe divergence of a vector field is proportional to the density of point sources of the field. In Gauss' law for the electric field. the divergence gives the density of point charges. In Gauss' law for the magnetic field. the zero value for the divergence implies that there are no point sources of magnetic field.
WebJan 9, 2024 · I have come across the differential form of Gauss's Law. ∇ ⋅ E = ρ ϵ 0. That's fine and all, but I run into what I believe to be a conceptual misunderstanding when evaluating this for a point charge. I know the math looks better in spherical coordinates, but I will be using Cartesian. So when I calculate the divergence I obtain: ∇ ⋅ E ...
