Electromagnetic phenomena cover most of the “electrical” aspects of “electrical engineering” and are fundamental to understanding a discipline of that discipline. Other relevant laws of physics include Newton’s law, photon quantization and the preservation of the relation of charge, energy, force and moment. This behavior can be precisely identified using Lorentz’s force law and Maxwell’s equations, which emerged from experiments that show how the forces of charge depend on the relative position and dynamics of other nearby charges. Electromagnetics involves the vacuum and the macroscopic behavior of electrical charge in matter.
