(N/A) Gauss's law in electrostatics states that the net electric flux through any closed surface is equal to the net charge enclosed by the surface divided by the permittivity of free space: $\oint \vec{E} \cdot d\vec{A} = \frac{q_{enclosed}}{\epsilon_0}$. This implies that electric charges exist as isolated monopoles.
Gauss's law in magnetism states that the net magnetic flux through any closed surface is always zero: $\oint \vec{B} \cdot d\vec{A} = 0$. This implies that magnetic monopoles do not exist and magnetic field lines always form continuous closed loops.
