After asking about Which of the properties of particles are intrinsic properties and why? it was commented "Charge, spin, lepton number, baryon number definitely. Mass maybe." and "is magnetic dipole moment really a separate property ?" What I'm wondering now is, that it seems to be that the magnetic dipole moment does not vanish in extreme situation whereas the electric charge gets weaker in bounded to the nucleus state by Screening effect.
This seems to happen not only inside the atom but also in the other extreme, the neutron stars. The charge of the electrons and the protons merge but the magnetic dipole moments don't go away. And the intrinsic spin also does not disappear and perhaps should not disappear because this two properties are related to each other. So perhaps in extrem situations the magnetic dipole moment of charged particles is the more stable property than the electric charge?
