In physics and electromagnetism, Gauss's law, also known as Gauss's flux theorem, (or sometimes simply called Gauss's theorem) is a law relating the distribution of electric charge to the resulting electric field. In its integral form, it states that the flux of the electric field out of an arbitrary closed surface is proportional to the electric charge enclosed by the surface, irrespective of ho… http://hyperphysics.phy-astr.gsu.edu/hbase/electric/laplace.html

WebAlternatively, the existence of A and ϕ is guaranteed from these two laws using Helmholtz's theorem.For example, since the magnetic field is divergence-free (Gauss's law for magnetism; i.e., ∇ ⋅ B = 0), A always exists that satisfies the above definition..
