# Gauss' Law of Magnetostatic Interpretation of Divergence of Magnetic Field-Maxwell's Equations

The magnetic flux through any surface is the surface integral of the normal component of , i.e.,

â€‹

As it is not possible to have an isolated magnetic pole, magnetic flux lines always close upon themselves. Thus, the total magnetic flux through a closed surface must be zero.

âˆ´ â€‹

This equation is known as
Applying the divergence theorem, we get

*the law of conservation of magnetic flux or the integral form of Gaussâ€™ law of magnetostatic fields*.â€‹

â€‹âˆ´

This is known as the

*differential form of Gaussâ€™ law of magnetostatic fields*which shows that magnetostatic fields have no sources or sinks and the magnetic field lines are continuous.
