* Dipole moment* can be defined as the product of magnitude of charge and the distance of separation between the charges.

**Dipole moment**may refer to:

- Electric dipole moment, the measure of the electrical polarity of a system of charges
- Magnetic dipole moment, the measure of the magnetic polarity of a system of charges
- Nuclear magnetic moment, the magnetic moment of an atomic nucleus

- Topological dipole moment, the measure of the topological defect charge distribution
- The second order coefficient of the multipole expansion of a function

“I have, thanks to my travels, added to my stock all the superstitions of other countries. I know them all now, and in any critical *moment* of my life, they all rise up in armed legions for or against me.”

—Sarah Bernhardt (1844–1923)
