Is there any deep reason for introducing the electromagnetic field tensor other than the fact that Maxwell's equations can be written in a very succinct form in terms of it? Would it be possible to write down a lagrangian involving a normal kinetic term for [tex] A^{\mu} [/tex] that reproduces the physics of electromagnetism correctly?(adsbygoogle = window.adsbygoogle || []).push({});
