Explanation of Displacement Current in a Vacuum
  It is considered that the time derivative of the electric intensity in the Maxwell-Ampere law (displacement current) denotes that a change of electric field generates a magnetic field. This paper shows that there is no reason to think a change of electric field generates a magnetic field and the displacement current term has a different meaning. It is necessary to be aware of distant conductors and their magnetic fields.
