four differential equations which form the foundation of classical electrodynamics, classical optics, and electric circuits

Maxwell's equations are four differential equations which form the foundation of classical electrodynamics, classical optics, and electric circuits.

a set of four equations that describe the behavior of electric and magnetic fields

Maxwell’s equations are a set of four equations that describe the behavior of electric and magnetic fields.

a set of coupled partial differential equations

Maxwell equations (otherwise known as maxwell theory) are a set of coupled partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism which deal with electromagnetic radiation, electromagnetic waves and electromagnetic force.

partial differential equations that relate the electric and magnetic fields to each other and to the electric charges and currents

Maxwell's equations are partial differential equations that relate the electric and magnetic fields to each other and to the electric charges and currents.
