Displacement current
In
electromagnetism
,
displacement current
is a quantity appearing in
Maxwell's equations
that is defined in terms of the rate of change of
electric displacement field
. Displacement current has the units of electric
current density
, and it has an associated
magnetic field
just as actual currents do. However it is not an electric current of moving
charges
, but a time-varying
electric field
. In materials, there is also a contribution from the slight motion of charges bound in atoms,
dielectric polarization
.
