This study proposes that a planetary center may represent the source of a single electromagnetic activity that appears in different geometric forms at different frequencies. The low-frequency component is associated with large-scale, approximately spherical electromagnetic organization, while higher-frequency components are proposed to appear as central/binding and planar-cyclic organization. In this model, satellite motion is interpreted as the visible motion form of the high-frequency planar electromagnetic activity, while the central/binding form is associated with gravity-like behavior. The Earth-Moon relation R²g ≈ rv² and, using v = 2πrf, R²g ≈ 4π²r³f² is presented as a mathematical correspondence compatible with, but not proof of, the proposed common central electromagnetic origin. The primary hypothesis is that one central electromagnetic activity undergoes frequency differentiation, producing distinct geometrical forms associated with spherical organization, binding, and cyclic motion.
