	~~'''Quadrupole magnets''' consist of groups of four [[magnet]]s laid out so that~~ in the ~~planar [[multipole expansion]]~~ of the ~~field~~ the ~~dipole terms cancel and where the lowest significant terms in the field equations~~ are ~~[[quadrupole]]~~. ~~Quadrupole magnets~~ are ~~useful as they create~~ a ~~[[magnetic field]] whose magnitude [[Linear function\|grows rapidly]]~~ with ~~the [[radius\|radial]] distance from its longitudinal [[Coordinate axis\|axis]]~~. ~~This is used~~ in ~~[[particle beam]] focusing~~.

	~~The simplest magnetic quadrupole is two identical bar magnets parallel to each other such that~~ the ~~north pole of~~ one ~~is next~~ to the ~~south of the other and vice versa~~. ~~Such a configuration would have no dipole moment, and its field will decrease at large distances faster than that~~ of a ~~dipole. A stronger version with very little external field involves using a ''k''=3 [[Halbach cylinder]].~~

	~~In some designs of quadrupoles using [[electromagnet]]s there are four [[steel]] pole tips: two opposing [[magnetic north pole]]s~~ and ~~two opposing magnetic south poles. The steel is magnetized by~~ a ~~large [[electric current]]~~ that ~~flows~~ in ~~the coils~~ of ~~tubing wrapped around the poles~~. ~~Another design is a [[Helmholtz coil]] layout~~ but ~~with the current in one of the coils reversed.<ref>~~[http://~~hyperphysics.phy-astr~~.~~gsu~~.~~edu~~/~~Hbase~~/~~magnetic/magquad.html Quadrupole Magnetic Field<!-- Bot generated title -->~~]~~</ref>~~

	~~At the speeds reached~~ in ~~high energy [[particle accelerator]]s, magnetic deflection is more powerful than electrostatic, and use of~~ the ~~magnetic term~~ of ~~the [[Lorentz force]]:~~

	~~is enabled with various magnets~~ that ~~make up '~~the ~~lattice' required~~ to ~~bend, steer~~ and ~~[[strong focusing\|focus]]~~ a ~~charged particle beam.~~

	[~~[File~~:~~Magnetic field of an idealized quadrupole with forces~~.~~svg\|thumb\|300px\|Magnetic field lines of an idealized quadrupole field in the plane transverse to the nominal beam direction~~. ~~The red arrows show the direction of the magnetic field while the blue arrows indicate the direction~~ of the ~~[[Lorentz force]]~~ on a ~~positive particle going into the image plane (away from the reader)]]~~

	~~The quadrupoles in the lattice are~~ of ~~two types: 'F quadrupoles' (which are horizontally focusing but vertically defocusing) and 'D quadrupoles' (which are vertically focusing but horizontally defocusing). This situation is due~~ to ~~the laws~~ of ~~[[electromagnetism]] (the [[Maxwell equations]]) which show that it is impossible for a quadrupole to focus in both planes at the same time~~. ~~The image on the right shows an example of a quadrupole focusing in the vertical direction for a positively charged particle going into the image plane (forces above~~ and ~~below the center point towards the center) while defocusing in the horizontal direction (forces~~ left ~~and right of the center point away from the center)~~.

	~~If an F quadrupole~~ and ~~a D quadrupole are placed immediately next~~ to ~~each other~~, ~~their fields completely cancel out (in accordance with [[Earnshaw's theorem]])~~. ~~But if there is a space between them (and the length~~ of ~~this has been correctly chosen)~~, ~~the overall effect~~ is ~~focusing~~ in ~~both horizontal~~ and ~~vertical planes. A lattice~~ can ~~then be built up enabling the transport of the beam over long distances—for example round an entire ring~~. ~~A common lattice is a FODO lattice consisting of a basis of a focusing quadrupole~~, ~~'nothing' (often a bending magnet), a defocusing quadrupole and another length of 'nothing'.~~

	~~==Mathematical description of~~ the ~~ideal field==~~

	~~The components~~ of the ~~ideal magnetic field in the plane transverse~~ to ~~the beam is given by (see also [[multipole magnet]]):~~

	: <~~math~~> ~~B_y = K \cdot x \qquad B_x = K \cdot y~~ <~~/math~~>

	if the ~~magnetic poles~~ are ~~arranged with an angle of 45 degrees~~ to the ~~horizontal and vertical planes~~. ~~<math>K</math>~~ is ~~the field gradient~~
	of the ~~vertical component~~ in ~~the horizontal direction (~~or ~~equivalently~~, the ~~field gradient of the horizontal component in~~ the ~~vertical direction). Its [[SI unit]] is <math>\mathrm{T}/\mathrm{m}</math>. The sign of <math>K</math> determines whether (~~for ~~a fixed particle charge and direction)~~ the ~~quadrupole focuses or defocuses particles in the horizontal plane~~.
