hi to everyone
L=T-V
as you know it is the lagrangian equation
the effective Lagrangian of the electromagnetic field is given by following relation in gaussian units.
L=(1/8pi) (E^2-B^2)
how is must calculate this relation?
(the energy density of electromagnetic fields is given by u=(1/8pi) (E^2+B^2) )
