TORRES DEL CASTILLO, G.F  y  MENDEZ GARRIDO, A. Torques on quadrupoles. Rev. mex. fis. [online]. 2006, vol.52, n.6, pp.501-506. ISSN 0035-001X.

Making use of the fact that a 2^l-pole can be represented by means of l vectors of the same magnitude, the torque on a quadrupole in an inhomogeneous external field is expressed in terms of the vectors that represent the quadrupole and the gradient of the external field. The conditions for rotational equilibrium are also expressed in terms of these vectors.

Palabras llave : Multipoles; torque.
