dipole moment




An electric dipole is a pair of equal and opposite electric charges a short distance apart. All ordinary manifestations of magnetism are the result of magnetic dipoles, whether these arise in the context of permanent magnets or electromagnets. In either case, the dipole moment is a vector quantity descriptive of the dipole. Atomic nuclei and asymmetric molecules often exhibit dipole or other multipole properties.
