Taking divergence of Ampere’s law shows it is not consistent with continuity equation. To be consistence with charge conservation, Maxwell added a “displacement current” to Ampere’s Law, and together with the other laws of electromagnetism, we call the

Unformatted text preview: Maxwell’s equations : Along with the Lorentz force law we know everything about classical electrodynamics. Maxwell’s equations tell us how EM fields are generated from charges and currents; Lorentz law tells us the forces exerted on charged particles by these EM fields. Second conservation law – conservation of energy...
