A ferromagnetic wire is able to capture superconducting particles for analytical studies. Here, we investigate (see movie) the abiltiy to move around superconducting spheres, a model system, for searching new material in inhomogenous ceramic reaction mixtures.

This work was carried out in the group of Prof. Jürg Hulliger.
