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.

Famous quotes containing the word fields:
“Forget about the precious sight
of my lover’s face
that steals away my heart.
Just seeing the borders
of the fields on the borders
of her village
gives me instant joy.”
—Hla Stavhana (c. 50 A.D.)
