a measure of the overall electric field associated with a molecule. Depends on (i) charges (or partial charges) and (ii) their separation. Units of debye (D). 1 D = 3.33E-30 Cm. A dipole moment of ~10 D corresponds to a +1 and -1 electron equivalent charge separated by 1 Angstrom. Typical molecular dipole moments range from zero to a few debye.

Electric dipole moment () is the product of the positive charge and the distance between the charges. Dipole moments are often stated in debyes; The SI unit is the coulomb metre. In a diatomic molecule, such as HCl, the dipole moment is a measure of the polar nature of the bond; i.e. the extent to which the average electron charges is displaced towards one atom (in the case of HCl, the electrons are attracted towards the more electronegative chlorine atom). In a polyatomic molecule, the dipole moment is the vector sum of the dipole moments of the individual bonds. In a symmetrical molecule, such as tetrafluoromethane (CF4) there is no overall dipole moment, although the individual C-F bonds are polar.

Measure of how polarized a molecule is (how large the dipole is).

NIA] For a transmitter, the product of the area of a coil, the number of turns of wire, and the current flowing in the coil. At a distance significantly larger than the size of the coil, the magnetic field from a coil will be the same if the dipole moment product is the same. For a receiver coil, this is the product of the area and the number of turns. The sensitivity to a magnetic field (assuming the source is far away) will be the same if the dipole moment is the same.

The product of the distance separating opposite charges of equal magnitude of the charge; a measure of the polarity of a bond or molecule; a measured dipole moment refers to the dipole moment of an entire molecule.

for a dipole (a positive charge and a negative charge separated by a small distance) a vector directed away from the negative to the positive charge whose magnitude is the product of the charge and the separation

Without qualification usually means electric dipole moment, the product of charge and separation distance of an (electric) dipole. Dipole moment is a vector, its direction determined by the position vector from the negative to the positive charge. Dipole moments (usually of molecules) are classified as permanent (the centers of positive and negative charge do not coincide even when subjected to no external field) and induced ( charge separation is a consequence of an external field acting in opposite directions on positive and negative charges). Water is often given as the prime example of a molecule with a permanent dipole moment. The magnetic dipole moment of a magnetic dipole is the product of the electric current in the loop and the area it encloses. Magnetic dipole moment also is a vector, its direction determined by the normal to the plane of the current loop, the sense of this normal specified by the right-hand rule.
