VARGUEZ-VILLANUEVA, E.; RODRIGUEZ-ZERMENO, V.  and  SOSA, V.. Calculation of vertical force between finite, cylindrical magnets and superconductors. Rev. mex. fis. [online]. 2008, vol.54, n.4, pp.293-298. ISSN 0035-001X.

The maximum force between a permanent magnet and a superconductor in the Meissner state has been calculated. The calculation was performed assuming the superconductor to be a perfect diamagnet and neglecting the London penetration depth. The resulting force takes into account the geometric dimensions of both the magnet and the superconductor. This constitutes an important improvement for the description of the maximum force attainable in these systems. The method can be applied in cases with azimuthal symmetry.
