…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 …

The meaning of QUADRUPOLE is a system composed of two dipoles of equal but oppositely directed moment.

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 …

Jan 2, 2025 · While calculations of the quadrupole moment for a given nuclei are beyond the scope of this page, the moments for the nuclei have been calculated and a few examples are …

Understand the concept of an electric quadrupole, its field distribution, and the mathematical representation of this phenomenon in physics.

Some of the confusion over factors of two, and "primitive" versus "traceless" comes from this use of the quadrupole moment as a coefficient in different expansions describing different properties.

Jun 9, 2023 · What are Quadrupole Fields? Quadrupole fields, on the other hand, are a bit more complex. They have two north poles and two south poles, creating a kind of four-pole setup. …

May 27, 2024 · The principle of an electric quadrupole involves a system of charges or the electric field’s distribution which forms a unique arrangement. This arrangement consists of two pairs …
