The method is then used to obtain the total energy and momentum for the electromagnetic field described by Maxwell electrodynamics, Born-Infeld nonlinear electrodynamics, and Podolsky generalized electrodynamics, respectively. © 1997 American Association of Physics Teachers.882-887engArtigo10.1119/1.18676WOS:A1997XU38600012Acesso restrito2-s2.0-00315070022-s2.0-0031507002.pdf
