I've been trying to obtain the EM stress energy tensor... but I'm not sure if what I got is correct.
In all the websites I googled, I found
[tex]T^{\mu\nu} =- \frac{1}{4}g^{\mu\nu} F^{\alpha\beta}F_{\alpha\beta} + F^{\mu}\,\!_{\lambda}F^{\nu\lambda}[/tex]
However, is this with the sources or without the sources? Seems to me that this is what I would get for a Lagrangian without current. what happens if I add a current density?
I just need a quick answer... I can't seem to find anything online.
