Classical electromagnetism
BRANCH OF THEORETICAL PHYSICS THAT STUDIES CONSEQUENCES OF THE ELECTROMAGNETIC FORCES BETWEEN ELECTRIC CHARGES AND CURRENTS
Classical electrodynamics; Classical Electrodynamics
Classical electromagnetism or classical electrodynamics is a branch of theoretical physics that studies the interactions between electric charges and currents using an extension of the classical Newtonian model. 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.
