The differential rotation of liquid polar caps caused by magnetospheric currents closing up under neutron star surface is considered. The anisotropy of electric conductivity and viscosity due to magnetic field is taken into account. It is shown that rotation velocity is small and almost all electric current close up deeper, inside rigid crust.
