<!--In [[physics]], a '''gauge principle''' specifies a procedure for obtaining an [[interaction term]] from a free [[Lagrangian]] which is symmetric with respect to a [[continuous symmetry]]—the results of localizing (or '''gauging''') the [[Gauge_theory#Global_and_local_symmetries|global symmetry group]] must be accompanied by the inclusion of additional fields (such as the [[electromagnetic field]]), with appropriate [[kinetic term|kinetic]] and [[interaction term]]s in the [[action (physics)|action]], in such a way that the extended Lagrangian is [[General covariance|covariant]] with respect to a new extended group of local transformations.
