The < b > Coulomb Gauge< / b > is specified by taking
2022-02-07 14:11:58 +00:00
\[
{\boldsymbol \nabla} \cdot {\boldsymbol A} = 0
\]
2022-03-15 09:07:27 +00:00
in which case < a href = "./emf_svp.html#Lapphi" > Lapphi< / a > becomes simply
2022-02-07 14:11:58 +00:00
\[
2022-03-15 09:07:27 +00:00
{\boldsymbol \nabla}^2 \phi = -\frac{\rho}{\varepsilon_0}
2022-02-07 14:11:58 +00:00
\]
2022-03-15 09:07:27 +00:00
< i > i.e.< / i > Poisson's equation, whose solution we already know:
2022-02-07 14:11:58 +00:00
\[
2022-03-15 09:07:27 +00:00
\phi({\boldsymbol r}, t) = \frac{1}{4\pi \varepsilon_0} \int d\tau' \frac{\rho({\boldsymbol r}^\prime, t)}{|{\boldsymbol r} - {\boldsymbol r}^\prime|}
2022-02-07 14:11:58 +00:00
\]
2022-03-15 09:07:27 +00:00
Note that this is an equal-time relationship (it does not mean instantaneous action at a distance, since \(\phi\) by itself is not physically measurable).

Although Gauss's law looks nice in the Coulomb gauge, Ampère-Maxwell does not:

\[

{\boldsymbol \nabla}^2 {\boldsymbol A} - \mu_0 \varepsilon_0 \frac{\partial^2 {\boldsymbol A}}{\partial t^2} = -\mu_0 {\boldsymbol J} + \mu_0 \varepsilon_0 {\boldsymbol \nabla} \left( \frac{\partial \phi}{\partial t} \right).
