| 21. | The active magnetic dipoles in this case are those of the electron shells of the paramagnetic atoms.
|
| 22. | There is an energy associated with a magnetic dipole moment in the presence of a magnetic field.
|
| 23. | The field does exert a torque on the magnetic dipole tending to align it with the field.
|
| 24. | The intrinsic electron magnetic dipole moment is approximately equal to the Bohr magneton " ?"
|
| 25. | A value of ? can also be extracted from the anomalous magnetic dipole moment of the muon.
|
| 26. | Thus an atom with unpaired electrons acts as a magnetic dipole and interacts with a magnetic field.
|
| 27. | On a micro scale, magnetic fields also affect moving electric charges in addition to magnetic dipoles.
|
| 28. | This pole model is also called the " Gilbert model " of a magnetic dipole.
|
| 29. | The assumption of a coaxial magnetic dipole field implies that only global scale structures can be simulated.
|
| 30. | Sometimes an atom has a net magnetic dipole moment even in the absence of an external magnetic field.
