  The spacial distribution of fields and currents in confining theories can
give direct evidence of dual superconductivity. We would like to discuss the
techniques for finding these properties and calculating the superconductivity
parameters in lattice simulations. We have seen dual Abrikosov vortices
directly in pure U(1) and SU(2) and others have also seen them in SU(3). In the
non-Abelian cases the system appears to be near the borderline between type I
and II. We also discuss the response of the supercurrents to external fields.
