Abstract
In this paper, we construct a single Lagrangian for both limits of Galilean
electrodynamics. The framework relies on a covariant formalism used in
describing Newton-Cartan geometry. We write down the Galilean conformal algebra
and its representation in this formalism. We also show that the Lagrangian is
invariant under the Galilean conformal algebra in d = 4 and calculate the
energy-momentum tensor.
