“…These motional fields can be expressed, for rectilinear motion, by the vector products of the parent fields and velocities of the bodies, but if the total resultant field in the interior of a moving body is due partly to the body itself and partly to external sources, the true motional field of the body must clearly be a function of the selfcomponent of field alone, and not of the resultant field in the body. This is consistent with Lorentz's extension of Maxwell's theory, in which he regarded electrons, moving freely in a fixed and immobile aether, as the sole sources of the electromagnetic field, 9 and in contrast to the earlier theory of Hertz, in which it was supposed that matter in motion carried the enclosed aether along with it, 10 This hypothesis of Hertz was found by A. Eichenwald in 1903-04 11 and H.A. Wilson in 1905 12 to be inconsistent with experiments which were in accord with Lorentz's theory.…”

An account is given of the relativistic component-field electromagnetic theory of moving bodies, which extends orthodox relativity theory by recognising sources of the field, and it is shown to have advantages over orthodox theory in aiding physical comprehension. It is then applied to the determination of the electromagnetic field in a cylindrical rod of nonretentive ferromagnetic material, which can be either a conductor or a dielectric, in motion with high velocity through crossed fields. Particular cases investigated include the electromotive force induced in the rod by its motion through a magnetic field, it being confirmed that this is independent of the relative permeability, and the magnetisation of the rod by its motion through an electrostatic field. Expressions for the polarisation and magnetisation of the moving rod are also obtained. All the results are considerably simplified if the velocity of the rod is small compared with the velocity of light. For low velocities the theory can be presented in simple terms without reference to the theory of relativity, and for this reason, and also because of its physical basis, it is considered to have considerable advantages.

“…Galilean electromagnetism raises severe doubts concerning our current understanding of the electrodynamics of moving media. Indeed, several experiments, like the ones by Roentgen [34], Eichenwald [35], Wilson [36], Wilson and Wilson [37], Trouton and Noble [38], etc., were believed to corroborate special relativity. As we will demonstrate for the Trouton-Noble experiment, there is not always a need for special relativity because the typical relative velocity in these experiments is well below the speed of light.…”

We discuss the seminal article in which Le Bellac and Lévy-Leblond have identified two Galilean limits of electromagnetism [1], and its modern implications. We use their results to point out some confusion in the literature and in the teaching of special relativity and electromagnetism. For instance, it is not widely recognized that there exist two well defined non-relativistic limits, so that researchers and teachers are likely to utilize an incoherent mixture of both. Recent works have shed a new light on the choice of gauge conditions in classical electromagnetism. We retrieve Le Bellac-Lévy-Leblond's results by examining orders of magnitudes, and then with a Lorentz-like manifestly covariant approach to Galilean covariance based on a 5-dimensional Minkowski manifold. We emphasize the Riemann-Lorenz approach based on the vector and scalar potentials as opposed to the Heaviside-Hertz formulation in terms of electromagnetic fields. We discuss various applications and experiments, such as in magnetohydrodynamics and electrohydrodynamics, quantum mechanics, superconductivity, continuous media, etc. Much of the current technology where waves are not taken into account, is actually based on Galilean electromagnetism.
