Electromagnetic Theory
Electromagnetic theory is the physical and mathematical framework describing electric and magnetic fields, their sources, and their interactions.
Overview
Classical electromagnetic theory brings electricity, magnetism, and light into a common framework through Maxwell’s equations. It describes how charges and currents produce fields, how fields interact with matter, and how electromagnetic waves propagate at the speed of light in vacuum. Static fields, induction, and radiation connect this framework to circuits, antennas, communications, and optical systems.
Why it matters
The theory enabled foundational technologies including wireless communication, electrical power engineering, and optical devices. Its relativistic invariance also served as a primary historical catalyst for special relativity and subsequent relativistic field theories.
