**Maxwell's equations** are a set of partial differential equations that, together with the Lorentz force law, form the foundation of classical electrodynamics, classical optics, and electric circuits. These in turn underlie modern electrical and communications technologies.

**Maxwell's equations** have two major variants. The "microscopic" set of

**Maxwell's equations** uses total

charge and total

current including the difficult-to-calculate

atomic level charges and currents in materials. The "macroscopic" set of

**Maxwell's equations** defines two new auxiliary fields that can sidestep having to know these '

atomic' sized charges and currents.
