Electrodynamic Fields
Electrodynamic fields are E-fields which do change with time, when charges are in motion.
An electric field can be produced, not only by a static charge, but also by a changing magnetic field. The electric field is given by:
in which B satisfies
and ∇× denotes the curl. The vector field B is the magnetic flux density and the vector A is the magnetic vector potential. Taking the curl of the electric field equation we obtain,
which is Faraday's law of induction, another one of Maxwell's equations.

“Luxurious Man, to bring his Vice in use,
Did after him the World seduce:
And from the fields the Flow’rs and Plants allure,”
