Maxwell stress tensor |
I'm trying to get an intuitive feel for what the Maxwell stress tensor
'means'. I understand that you can integrate it over a bounding surface
and it will give you the net force on charged particles within that
volume. I've heard, though, that the maxwell stress tensor came about by
viewing the EM field as a fluid and considering tensions and pressures
within that fluid. Can anyone elucidate this point of view, or provide
any other intuitive explanations of the meaning and application of the
maxwell stress tensor?
thanks,
Tobin

Also, see section 284 in Clifford Truesdell's "Classical Field Theories"
section of the Handbook of Physics, not sure of the volume...
