Maxwell's stress tensor
Web11 mei 2024 · If you vary the action wrt the EM 4-potential, you get Maxwell’s equations with the source term depending on the charges. The GR situation is completely analogous. The stress-energy tensor is the source term of the EFEs, which are analogous to Maxwell’s equations, and therefore result from variation wrt the metric.

Web24 sep. 2016 · The goal is to obtain the force and the torque over a particle that is illuminated by an electromagnetic wave. The force is obtained by integration of the quantity dnTx over a surface that surrounds the particle. However, I cannot implement the torque because I cannot have access to the Maxwell stress tensor components.
