In this video, we directly calculate the stress-energy tensor for a vector field using the standard formula from Lagrangian field theory.
Using the electromagnetic field as our main example, we:
Start from the Lagrangian density. Apply the stress-energy tensor definition. Carefully handle index contractions. Comment on symmetry and physical meaning.
This video is perfect for students studying field theory, electrodynamics, or preparing for advanced topics like general relativity and quantum field theory.
