Maxwell's equations VS. Lorentz & Coulomb force equations

You can think of maxwells equations as equations of motion for the field, and the lorentz force as EOM for the currents. If you are looking for a single equation, it is the EM lagrangian, which will get you to all the equations of motion for the field and currents.
