Symmetries of the nonrelativistic electrodynamics are studied. It is shown that equations describing the Galilean electromagnetism in the presence of sources hold invariant under the ℓ–conformal Galilei group for an arbitrary (half)integer parameter ℓ. The group contains a transformation which links an inertial frame of reference to that moving with a constant acceleration of order up to 2 ℓ − 1 , thus pointing at potential dynamical instability of the system.
