Covariant formulation of classical electromagnetism

The covariant formulation of classical electromagnetism is a way of describing electromagnetic phenomena using the principles of special relativity. It reformulates Maxwell's equations and the governing equations of electromagnetism in a covariant framework, allowing them to be consistently expressed in any inertial frame of reference. ### Key Components: 1. **Four-Vectors**: In the covariant formulation, physical quantities are represented as four-vectors and tensors.
