Covariant formulation of classical electromagnetism

Covariant formulation of classical electromagnetism is a way to look at electricity and magnetism. Every day, we experience different things that have to do with electricity and magnetism - like TV and radio, power lines, and even the Earth's magnetic field! To understand them all better, scientists used a special language called mathematics. In this language, they created a special equation called Covariant Formulation of Classical Electromagnetism. This equation explains how electricity and magnetism can be described together. It helps us figure out the rules of electricity and magnetism, and how they interact with each other. Now scientists can look at the behavior of both electricity and magnetism together and figure out how they work.
