EM stress energy tensor

  1. Oct 12, 2008 #1
    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.

    thanks, got my answer, indeed that form above is without any source. A term proportional to the product of AJ are included, as expected.
