  • Quadrupole - Wikipedia
    A quadrupole or quadrapole is one of a sequence of configurations of things like electric charge or current, or gravitational mass that can exist in ideal form, but it is usually just part of a multipole expansion of a more complex structure reflecting various orders of complexity
  • 3. 8: Quadrupole Moment - Physics LibreTexts
    The system possesses what is known as a quadrupole moment While a single charge is a scalar quantity, and a dipole moment is a vector quantity, the quadrupole moment is a second order symmetric tensor
  • Quadrupole Moment - (Intro to Astronomy) - Vocab, Definition . . . - Fiveable
    The quadrupole moment is a measure of the deviation of an object's charge distribution from spherical symmetry It is a higher-order multipole moment that describes the degree to which an object's charge distribution departs from a perfect sphere or point charge
  • Quadrupole Moment and Potential - Brigham Young University
    𝑄 Ü Ý is called the “quadrupole moment,” also the “quadrupole moment tensor ” Since 𝑖 and 𝑗 can each be 𝑥, 𝑦, or 𝑧, it is a collection of nine numbers which can be written as a 3×3 matrix, just like 𝐩 can be written as a 3-element vector
  • Electric Quadrupole - HyperPhysics
    Electric Quadrupole A general distribution of electric charge may be characterized by its net charge, by its dipole moment, its quadrupole moment and higher order moments An elementary quadrupole can be represented as two dipoles oriented antiparallel One of the most common uses of the electric quadrupole is in the characterization of nuclei
  • Quadrupole | physics | Britannica
    …of focusing magnet is a quadrupole, a magnet built with four poles (two norths and two souths) arranged opposite each other This arrangement pushes particles toward the centre in one direction but allows them to spread in the perpendicular direction
  • Quadrupole Moment: Definition Explanation - Physics Forums
    for a symmetric quadrupole aligned along the z (or 3) axis, having quadrupole moment Q_0 There is a full discussion of quadrupoles in Section 2 4 of Franklin, "Classical Electromagnetism" (AW com)
  • Electric Quadrupole | Principles, Applications Theory
    An electric quadrupole is a sophisticated concept in the realm of physics and electromagnetism, significantly extending beyond the simpler notions of electric monopoles (like charges) and dipoles (like magnets)
  • Quadrupole moment equation – Electricity – Magnetism
    Concept of Quadrupole Moment In simple terms, a quadrupole consists of two dipoles, with equal but opposite charges or magnetic poles The quadrupole moment, therefore, quantifies the distribution of these charge or pole densities within a system
  • Quadrupole - an overview | ScienceDirect Topics
    Quadrupole is a type of mass analyzer with the best performance except for magnetic analyzer It has many advantages such as small size, light weight, low cost and mature technology
