A sextupole magnet is a type of electromagnet or permanent magnet that produces a magnetic field with a sextupole configuration. In terms of multipole fields, a sextupole refers to the term in the multipole expansion that has a magnetic field that varies with the third power of the distance from the center, typically noted as \\(B\\) (magnetic field strength) depending on the radial position \\(r\\) as \\(B \\propto r^3\\).
