Determination of the Influence Forces Affecting the Surface Layers of the Rotating Magnetic Neutron Stars

This work aims to study the physical properties of Neutron stars. The effect of magnetic forces and the ratio of accelerations on surface layers are determined. Goldriech and Julian model is considered. The magnetic field evolution within light cylinder can contribute to explain the physical mechanism generating the electromagnetic forces with other forces like gravitation and centrifugal acceleration. The ratio between them will be determined for r ≫ R. The centrifugal and gravitation terms can be neglected. The centrifugal and electromagnetic forces would become comparable at r~10
⁴
R, the gravitational term is negligible. The results showed that the electric forces would pull out charged particles from surface, unless the work function and cohesive forces are unrealistically large. The calculations estimated that a vacuum space regions surrounding Neutron stars implies a huge forces acting on the surface layers. The typical number density of particles (Ngj) quickly decreases with distance due to the magnetic field dependence (B~10
^-3
). The magnetic field is distorted beyond light cylinder limits.
