'''Displacement current''' is the term James Clerk Maxwell added to Ampère's law in 1865, representing the contribution of a time-varying electric field to the magnetic field — even in the absence of electric charges or conduction current. It was not derived from any experimental observation. It was derived from theoretical necessity: without it, [[Charge Conservation|charge conservation]] would be violated in time-dependent situations. The displacement current completed the symmetry of [[Maxwell's Equations|Maxwell's equations]] and, in doing so, predicted the existence of electromagnetic wave propagation in vacuum.

The physical meaning of displacement current was controversial for decades. It appeared to describe a current flowing through empty space — a concept that violated the intuitions of mechanistic physics, which demanded that all physical effects be transmitted by material substances. Maxwell's introduction of the term marked a decisive break from the mechanical worldview and toward the field-theoretic conception of nature that would dominate twentieth-century physics. The displacement current is proportional to the rate of change of electric flux and depends on the [[Vacuum Permittivity|vacuum permittivity]] of the medium.
