Abstract
Lattice studies indicate existence of magnetic strings in QCD vacuum. We argue that recently found non-Abelian strings with rich world-sheet dynamics provide a pattern which fits the strings observed on the lattice. In particular, within this pattern we explain the localization of the monopole-antimonopole pairs on the magnetic string world sheet and the negative contribution of the magnetic strings into the vacuum energy and gluon condensate. We suggest the D2 brane realization of the magnetic string which explains the temperature dependence of its tension.
