This paper develops a phenomenological model of nucleon structure based on the Kelvin-Voigt (K-V) mechanical analogy for Maxwell's equations. Each nucleon (proton or neutron) is represented as a single Hill-type vortex in a viscoelastic medium, divided into two concentric zones: a compact inner core and an extended outer mantle. The sizes of these zones are taken directly from classic electron-scattering data on the charge distribution inside the proton and neutron. Within the K-V framework, both the electric charge and the magnetic moment of a vortex arise from the same underlying rotation. Requiring each zone to carry equal charge leads, without any free parameters, to a simple geometric prediction: the ratio of the two zones' magnetic moments must equal the ratio of their radii. This prediction agrees quantitatively with experiment. The model is then applied to strange baryons. For the Lambda hyperon, it yields a falsifiable relation between the magnetic and charge form factors, testable at future electron-hyperon scattering facilities. For the Sigma triplet, the equal-charge ansatz is found to be quantitatively inconsistent with measured magnetic moments, implying that the charge-distribution geometry differs from the nucleon case. For the Xi doublet, the ansatz produces no physical solution at all, suggesting a qualitatively different internal structure - possibly involving more than two zones or a different vortex topology. The pattern of outcomes across the baryon octet - exact success at zero strangeness, partial failure at one unit of strangeness, and complete failure at two - is itself interpreted as a systematic diagnostic of how strange quarks modify baryon structure, and motivates concrete experimental targets at facilities such as PANDA at FAIR. The model is explicitly phenomenological and is not proposed as a fundamental theory, but offers an intuitive geometric picture that may be valuable for educational purposes.
