The dynamics of magellanic stream (MS) as a series of clouds
extend from the magellanic clouds (MCs) to the south Galactic pole
is affected by the distribution and the amount of matter in the
Milky Way. A quasi-steady model for the flow of the gas is used
for describing the dynamics of MS. The gravitational effect of
power law halo model including the corresponding disk and bulge on
the MS is calculated and compared with the observation. Amongst
eight Galactic models, the thick disk model has the most
compatibility with the observation. The gravitational effect of
MCs induces a gradient on the column density along the MS that
compared with the observation results a mass of 1.4 ×1010M\odot for the MCs.
