## Maxwell’s Equations: Differential form of Gauss’s Law for Magnetic Field

Gauss’s Law in differential form states that

The divergence of magnetic field at any point is zero

Now in case of differential form of Gauss’s law for electric fields divergence of electric field is proportional to electric charge density but here in case of magnetic fields divergence of field at any point is zero because here it is not possible to have isolated magnetic poles as magnetic poles always appear in pair of north and south poles. So there is no such thing as magnetic charge density and this means that divergence of magnetic field is zero.
