Covariant formulation of electrodynamics

Covariant formulation of electrodynamics refers to expressing the laws of electricity and magnetism in a way that remains unchanged regardless of the observer's motion or frame of reference. This approach combines electric and magnetic fields into a unified framework using mathematical objects called tensors. It ensures that the fundamental principles are consistent for all observers, reflecting the symmetry of space and time. This formulation is essential in the context of Einstein's theory of relativity, where it accommodates the effects of gravity on electromagnetic phenomena, ensuring that they are understood in the same consistent framework.
