The structure of the flux tube is studied in SU(2) QCD from the standpoint
of the abelian projection theory. It is shown that the flux distributions of
the orthogonal electric field and the magnetic field are produced by the effect
that the abelian monopoles in the maximally abelian (MA) gauge are expelled
from the string region.Comment: 3 pages, uuencoded compressed file, contribution to Lattice '9
