In this paper, we demonstrate that through an elasto-mechanical relationship and the Navier-Stokes equation, a magnetic monopole can be introduced as a volume flux following deformation.This phenomenon is linked to mass generation. By incorporating the magnetic monopole, wederive Maxwell’s equations for the magnetic monopole, the electromagnetic waves equation, andwe give the Lagrangian formulation. An alternative Lagrangian is also presented, introducingCP violation, the breaking of electromagnetic dual symmetry, and a topological invariant. Themonopole results are employed to derive the relativistic mass-energy equation and reinterpretrelativistic outcomes. Specifically, the reinterpretation of the event interval enables us to revisit therelativistic metric in elastomechanical terms, related to the longitudinal and transverse speeds oflight as defined by Lam´e parameters. For an isotropic medium, the Lam´e parameters are spatiallyinvariant, corresponding to the validity of the Minkowski metric and constant inertial mass inspace. Under anisotropic conditions, the metrics of general relativity are derivable, with inertialmass dependent on spatial coordinates and its gradient described by the convective derivativeof longitudinal velocity. Furthermore, we demonstrate that the magnetic continuity equationpredicts the fundamental equations of quantum mechanics in the Bohmian interpretation. Finally,evaluating Dirac quantization as predicted by quantum mechanics reveals its incompatibility withthe hypothesis of inertial mass. However, is possible to correct this inconsistency by consideringthe general mass formula obtained from magnetic monopole considerations
