This article constitutes the second part of the series "Space-Time" from a Realist Perspective. Continuing the analysis developed in the first part, the present work primarily aims to examine the compatibility between classical mechanicsand electromagnetism, with particular attention to the relationship between Galilean transformations and Maxwell’s equations, an issue traditionally presented as one of the main motivations for introducing Lorentz transformations and formulating the Theory of Special Relativity. It is investigated whether the alleged incompatibility between thesetheoretical frameworks necessarily arises from physical phenomena or is instead related to the way the electromagnetic and kinematic quantities involved are interpreted. To guide this analysis, principles underlying the adopted approachare first established. Based on these principles, the concept of spacetime interval in the Einsteinian relativistic formulation and its invariance under coordinate transformations are examined. Subsequently, the relationship betweenGalilean transformations and Maxwell’s equations is analyzed, including the invariance of these equations under Galilean transformations and the transformations of the electric and magnetic fields between reference frames in relative motion. In addition, the conventional interpretation of the phenomenon of magnetic induction is examined. This second part remains restricted to the theoretical, mathematical, and conceptual analysis of these issues. Thediscussion of the main experiments and observations traditionally presented as confirmations of Einsteinian relativity will be developed in the third and fourth parts of the series.
