Electric Field - Electrodynamic Fields

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.
