Displacement Current
Displacement current
is a term introduced by James Clerk Maxwell to account for the
changing electric field
in the
continuity equation
of Ampère's law, allowing it to be consistent with the
conservation of charge
. It is not an
actual current of moving charges
but rather a
mathematical construct
that explains how a
time-varying electric field
can produce a
magnetic field
, thus completing
Maxwell's equations
and leading to the
prediction of electromagnetic waves
.
