In relativistic physics, the electromagnetic stress-energy tensor is the contribution to the stress-energy tensor due to the electromagnetic field. The stress-energy tensor describes the flow of energy and momentum in spacetime. The electromagnetic stress-energy tensor contains the negative of the classical Maxwell stress tensor that governs the electromagnetic interactions. == Definition == === SI units === In free space and flat space-time, the electromagnetic stress-energy tensor in SI units is T μ ν = 1 μ 0 [ F μ α F ν α − 1 4 […]
