We study the interaction between a one dimensional magnetic nanostructure and a thin film superconductor. It is shown that different magnetic distributions produce characteristic magnetic field signatures. Moreover, the magnetic structure can induce a weak link in the superconducting film, or be positioned directly above a predefined nonsuperconducting weak link. We estimate the magnetic flux associated with such a structure, and discuss a general expression for the energy calculated within the London model.
