11. The intrinsic electron magnetic dipole moment is approximately equal to the Bohr magneton " ?" 12. A value of ? can also be extracted from the anomalous magnetic dipole moment of the muon. 13. Sometimes an atom has a net magnetic dipole moment even in the absence of an external magnetic field. 14. In the physically correct Amp�re model, magnetic dipole moments are due to infinitesimally small loops of current. 15. The magnetization field of a region points in the direction of the average magnetic dipole moment in that region. 16. In paramagnetic materials, the magnetic dipole moments of individual atoms spontaneously align with an externally applied magnetic field. 17. Its development started in early 1990s with susceptibility, magnetic dipole moment , and many additional molecular and solid state properties. 18. A permanent magnet, such as a bar magnet, owes its magnetism to the intrinsic magnetic dipole moment of the electron. 19. It is mainly a magnetic dipole moment ; the quadrupole moment does cause some small shifts in the hyperfine structure as well. 20. More precisely, to account for solenoids with many turns the unit of magnetic dipole moment is Ampere-turn meter 2.
