  2. Displacement current - Wikipedia

    en.wikipedia.org/wiki/Displacement_current

    This polarization is the displacement current as it was originally conceived by Maxwell. Maxwell made no special treatment of the vacuum, treating it as a material medium. For Maxwell, the effect of P was simply to change the relative permittivity ε r in the relation D = ε 0 ε r E. The modern justification of displacement current is ...

  3. Maxwell's equations - Wikipedia

    en.wikipedia.org/wiki/Maxwell's_equations

    Maxwell's addition states that magnetic fields also relate to changing electric fields, which Maxwell called displacement current. The integral form states that electric and displacement currents are associated with a proportional magnetic field along any enclosing curve.

  4. Electric flux - Wikipedia

    en.wikipedia.org/wiki/Electric_flux

    ε 0 is the electric constant (a universal constant, also called the permittivity of free space) (ε 0 ≈ 8.854 187 817 × 10 −12 F/m) This relation is known as Gauss's law for electric fields in its integral form and it is one of Maxwell's equations.

  5. Permittivity - Wikipedia

    en.wikipedia.org/wiki/Permittivity

    The size of the displacement current is dependent on the frequency ω of the applied field E; there is no displacement current in a constant field. In this formalism, the complex permittivity is defined as: [19] [20]

  6. Ampère's circuital law - Wikipedia

    en.wikipedia.org/wiki/Ampère's_circuital_law

    The second term on the right hand side is the displacement current as originally conceived by Maxwell, associated with the polarization of the individual molecules of the dielectric material. Maxwell's original explanation for displacement current focused upon the situation that occurs in dielectric media.

  7. Electric displacement field - Wikipedia

    en.wikipedia.org/wiki/Electric_displacement_field

    In physics, the electric displacement field (denoted by D), also called electric flux density or electric induction, is a vector field that appears in Maxwell's equations. It accounts for the electromagnetic effects of polarization and that of an electric field , combining the two in an auxiliary field .
