In its original form, Ampère's Circuital law relates the magnetic field <math>\mathbf{H}</math> to its source, the current density <math>\mathbf{J}</math>:

The [[right hand grip rule]] is a mnemonic for visualizing the orientation of the magnetic field <math>\mathbf{H}</math> encircling the current density <math>\mathbf{J} </math>.

 

[[James Clerk Maxwell]] conceived of [[displacement current]] as a polarization current in the dielectric vortex sea which he used to model the magnetic field hydrodynamically and mechanically. He added this [[displacement current]] to Ampère's Circuital law at equation (112) in his 1861 paper [http://vacuum-physics.com/Maxwell/maxwell_oplf.pdf On Physical Lines of Force].
