# 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 the law of conservation of magnetic flux or the integral form of Gaussâ€™ law of magnetostatic fields.

Applying the divergence theorem, we get
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.
