(N/A) Gauss's law for electrostatics is given by:
$\oint \vec{E} \cdot d\vec{S} = \frac{q_{enclosed}}{\varepsilon_{0}}$
Where $\vec{E}$ is the electric field and $q_{enclosed}$ is the net charge enclosed by the Gaussian surface.
Gauss's law for magnetism is given by:
$\oint \vec{B} \cdot d\vec{S} = 0$
Where $\vec{B}$ is the magnetic field.
The fundamental difference is that for electrostatics,the net electric flux through a closed surface is proportional to the enclosed charge,implying the existence of electric monopoles (charges). For magnetism,the net magnetic flux through any closed surface is always zero,which implies that isolated magnetic monopoles do not exist; magnetic field lines always form continuous closed loops.
