The Columbia Encyclopedia, Sixth Edition
electrodynamics study of phenomena associated with charged bodies in motion and varying electric and magnetic fields (see charge ; electricity ); since a moving charge produces a magnetic field , electrodynamics is concerned with effects such as magnetism , electromagnetic radiation , and electromagnetic induction , including such practical applications as the electric generator and the electric motor. This area of electrodynamics, often known as classical electrodynamics, was first systematically explained by the physicist James Clerk Maxwell. Maxwell's equations, a set of... Read more
