electric dipole moment

noun

, Electricity.

1. a vector quantity associated with two equal charges of opposite sign separated by a specified distance, having magnitude equal to the product of the charge and the distance between the charges and having direction from the negative to the positive charge along the line between the charges.

Example Sentences

The scientists zapped the molecules with lasers and studied the light reflected back by the molecules; bends in the light would point to an electric dipole moment.

From Scientific American

Theoretical models of physics predict that the electron will also have a very small electric dipole moment.

From Science Magazine

The rotating-bias-field technique may enable using trapped polar molecules for precision measurement and quantum information science, including the search for an electron electric dipole moment.

From Science Magazine

The result came from a search for the so-called electric dipole moment in the electron.

From Scientific American

"But theorists are very creative and would probably come up with models where the electric dipole moment is smaller."
