Electromagnetism and Relativity

Special relativity is one of the most well-verified theories in physics, rooted in the principles of electromagnetism. The relationship between electric and magnetic fields varies depending on the observer's reference frame, revealing a fascinating interplay that is captured by a covariant formulation of classical electromagnetism. This understanding is encapsulated in the electromagnetic tensor, which illustrates how different observers can perceive electric and magnetic phenomena differently based on their unique perspectives.
