Question
What are Maxwell’s equations for charges and currents in vacuum?
✓
Answer
$\int \vec{E} \cdot \overrightarrow{ dS }=\frac{ Q _{ in }}{\varepsilon_0}$
$\int \overrightarrow{ B } \cdot \overrightarrow{ dS }=0$
$\int \overrightarrow{ E } \cdot \overrightarrow{ d l}=-\frac{ d \phi_{ m }}{ dt }$
$\int \overrightarrow{ B } \cdot \overrightarrow{ d l}=\mu_0 I +\varepsilon_0 \mu_0 \frac{ d \phi_{ E }}{ dt }$
