Abstract:

The differential rotation of liquid polar caps caused by magnetospheric currents closing up under neutron star surface has been considered. The anisotropy of cap electric conductivity and viscosity due to magnetic field was taken into account. The rotation velocity was shown to be very slow and almost all electric current was brought out to close up deeper, inside the rigid crust.
