Neutrinos, while electromagnetically inert in the Standard Model, acquire electromagnetic properties through quantum loop effects, including magnetic moments, electric dipole moments, charge, and charge radii. This talk explores three core aspects: the magnetic moment of neutrinos as a direct consequence of their masses, with implications for model building; the impact of new leptonic symmetries decoupling mass and magnetic moment; and the anomalous electromagnetic properties shared between charged leptons and neutrinos. The astrophysical ramifications of these properties are also examined. Results are based on [1–8].
