Electromagnetics
Electromagnetics is a branch of study in physics that describes the interaction of things with electricity and magnetism. Initially, the subjects of electricity and magnetism were completely separate. However, Ørsted, Ampère, and Faraday discovered phenomena that linked those subjects, and Maxwell finally established a well-known set of equations called Maxwell’s equations in 1865. Since then, electricity and magnetism have been indistinguishably interwoven, and “electromagnetism” has been used to describe their intertwined phenomena. With Lorentz’s force law, Maxwell’s equations form the solid foundation of classical electromagnetics, electronics, photonics, and even quantum mechanics.
