electrodynamics
Charge and motion
Electrodynamics is the branch of physics dealing with the interactions between electric currents and magnetic fields, and with electromagnetic radiation.
Classical electrodynamics, formalized by Maxwell's equations, describes how charged particles produce and respond to electromagnetic forces.
Quantum electrodynamics extends this to subatomic scales, explaining how light and matter interact.
