Induced electric field

Varying magnetic excitation of the electric field induced electric field or Vortex electric field.

Magnetic field coil produces a sense of electromotive conductor regardless of the kind, shape, nature and composition, is caused by the change of the magnetic field itself. Maxwell's proposed "changes its inspired the space surrounding an electric field, the magnetic field, is this farm that makes closed-loop in the induced electromotive force and induced current" theory, called Eddy electric field and the electric field.

Induced electric field of electric field lines are closed, it has no beginning, end. Closed change of electric field lines surrounding magnetic field.
