Gauss's law for magnetism
  قانون ِ گاؤس در مغنات‌مندی  
qânun-e Gauss dar meqnâtmandi
Fr.: loi de Gauss en magnétisme  

The → magnetic flux through an arbitrary closed surface equals zero. Mathematically, in differential form: ∇ . B = 0 and in integral form: ΦB = ∫B.dS = 0 (closed surface integral). This is one of the four → Maxwell’s equations. This law expresses the fact that there are no free magnetic poles (→ monopoles) in nature and that all the lines of force of a magnetic field are closed curves.
