One describes the relation between electric flux and charge on an enclosed surface.  
One describes the relation between electric flux and charge on an enclosed surface.  One describes the relation between magnetic flux through an area enclosed by a closed and the electric field induced along the loop.  Another relates the circulating magnetic field to the electric current in a closed loop.  And the last describes the structure of a magnetic field. Including Gauss' Law, Faraday's Law of Induction, and Ampere's Law, FTP, identify this set of formulas named for the Scottish scientist who grouped them together.
