Gauss's law in magnetism : It states that the surface integral of the magnetic field \\\\(\\overset{\\rightarrow}{B}\\\\) over a closed surface S is equal zero. \\\\(\\phi \\overset{\\rightarrow}{B}.\\overset{\\rightarrow}{dS}=0\\\\)Gauss's law indicates that there are no sources or sinks of magnetic field inside a closed surface.
