In physics, Gauss's law for magnetism is one of the four Maxwell's equations that underlie classical electrodynamics. It states that the magnetic field B has divergence equal to zero, [1] in other words, that it is a solenoidal vector field. It is equivalent to the statement that magnetic monopoles do not exist. [2]Zero divergence does not imply the existence of a vector potential. Take the electric field of a point charge at the origin in 3-space. Its divergence is zero on its domain (3-space minus the origin), but there is no vector potential for this field. If there were, Stokes's theorem would tell us that the flux of the field around the unit ...
