classical electromagnetism

Also known as electrodynamics, electromagnetic field theory

branch of theoretical physics that studies consequences of the electromagnetic forces between electric charges and currents

AI overview

Classical electromagnetism is the branch of physics that explains how electric charges and electric currents create forces that affect each other and the world around them. It matters because these electromagnetic forces shape much of the technology we use daily, from electricity and magnetism to radio and light.

Classical electromagnetism or classical electrodynamics is a branch of physics focused on the study of interactions between electric charges and currents using an extension of the classical Newtonian model. It is, therefore, a classical field theory. The theory provides a description of electromagnetic phenomena whenever the relevant length scales and field strengths are large enough that quantum mechanical effects are negligible. For small distances and low field strengths, such interactions are better described by quantum electrodynamics which is a quantum field theory.
