However, beyond scaling arguments, the 'electric' and 'magnetic' labels can also be as- cribed a geometric basis dictated by how a Lorentzian theory is null-reduced [44]. While the method of null reduction is well-established in the literature and has been extensively employed to construct Galilean-invariant field theories, its Carrollian counterpart has been developed quite recently in [45] and [46].
