A Skyrmion is a topologically stable field configuration, originally introduced by Tony Skyrme, a nuclear physicist, who interpreted a proton as a "knot" in pion fields. Recently, the two-dimensional version of such Skyrmions was visualized as a lattice of vortices in the magnetic structure of manganese silicide (MnSi) We investigate theoretically the interaction between the applied electrical currrents and the topological magnetic structure.
