  We propose a method for the determination of magnetic monopole currents in
non-Abelian gauge theories which does not need a projection to Abelian degrees
of freedom. With this definition we are able to determine the distribution of
magnetic currents and electric fields for the gluonic flux tube between a pair
of static charges. Further we check the validity of the Gauss law and the dual
London equation in a gauge invariant formulation.
