| 21. | Under normal circumstances, even polar materials do not display a net dipole moment.
|
| 22. | Spherical top molecules have no net dipole moment.
|
| 23. | The molecules may remain neutral in charge, yet an electric dipole moment forms.
|
| 24. | Then the magnitude of the magnetic dipole moment is
|
| 25. | Where \ vec { d } is the dipole moment operator of the atom.
|
| 26. | These dipole moments generate an electric field that in turn generates measurable electric current.
|
| 27. | As such, the SI unit of magnetic dipole moment is ampere meter 2.
|
| 28. | It is this calculation that account for the anomalous magnetic dipole moment of fermions.
|
| 29. | If it has permanent dipole moment then magnetic properties depend upon orientation of dipoles.
|
| 30. | The dipole moment is 1.506 Debye.
