Dipole - Wikipedia
WEBDipole. The magnetic field of a sphere with a north magnetic pole at the top and a south magnetic pole at the bottom. By comparison, Earth has a south magnetic pole near its north geographic pole and a north magnetic pole near its south pole. In physics, a dipole (from Greek δίς (dis) 'twice', and πόλος (polos) 'axis' [1] [2] [3]) is an ...

WEBJan 13, 2020 · Anne Marie Helmenstine, Ph.D. Updated on January 13, 2020. A dipole is a separation of opposite electrical charges. A dipole is quantified by its dipole moment (μ). A dipole moment is the distance between charges multiplied by the charge. The unit of the dipole moment is the debye, where 1 debye is 3.34×10 −30 C ·m.

WEBA dipole is a distance r r from an infinitely-long line of negative charge of density λ λ. The dipole moment p→ p → is parallel to the line of charge. Find the magnitude of the torque on the dipole in terms of r r, p→ p →, and λ λ. The dipole moment is now pointing directly at the line of charge (perpendicular to it).
Dipole Moments - Chemistry LibreTexts
WEBJan 30, 2023 · Dipole Moments. Page ID. Dipole moments occur when there is a separation of charge. They can occur between two ions in an ionic bond or between atoms in a covalent bond; dipole moments arise from differences in electronegativity. The larger the difference in electronegativity, the larger the dipole moment.

WEBSep 12, 2022 · Induced Dipoles. Neutral atoms are, by definition, electrically neutral; they have equal amounts of positive and negative charge. Furthermore, since they are spherically symmetrical, they do not have a “built-in” dipole moment the way most asymmetrical molecules do.
Dipole–dipole forces (video) | Khan Academy
WEBAbout. Transcript. Dipole-dipole forces occur between molecules with permanent dipoles (i.e., polar molecules). For molecules of similar size and mass, the strength of these forces increases with increasing polarity. Polar molecules can also induce dipoles in nonpolar molecules, resulting in dipole–induced dipole forces.
Electric dipoles & dipole moments (video) | Khan Academy
WEBTranscript. Two equal and opposite charges separated by some distance constitute a dipole. The product of the charge and distance between them is called the dipole moment. Dipole moment represents the strength of the dipole. The electric field generated by the dipole is proportional to the dipole moment. Let's explore more about dipoles and ...

Dipole-Dipole Interactions - Chemistry LibreTexts
WEBJan 30, 2023 · Dipole-Dipole interactions result when two dipolar molecules interact with each other through space. When this occurs, the partially negative portion of one of the polar molecules is attracted to the partially positive portion of the second polar molecule.
What Is A Dipole? What Is Dipole Moment? - Science ABC
WEBOct 19, 2023 · A dipole is a substance that incorporates two equal and opposite charges (possessing a charge can be thought of as possessing some amount of energy). The charge can be electric, magnetic or any other type. Everything has two sides. This is the law of nature that has been followed since the beginning of time.
