Difference between Current density and Maxwell's equations

Current density vs. Maxwell's equations

In electromagnetism, current density is the electric current per unit area of cross section. Maxwell's equations are a set of partial differential equations that, together with the Lorentz force law, form the foundation of classical electromagnetism, classical optics, and electric circuits.
