**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:

“The need to exert power, when thwarted in the open *fields* of life, is the more likely to assert itself in trifles.”

—Charles Horton Cooley (1864–1929)
