Abstract
Due to the existence of both observational and theoretical evidences for the presence
of non-dipolar NS magnetic fields, it has become more and more clear that neutron
stars posses magnetic field structures, which are much more complicated than the
simple assumption of a dipolar neutron star (NS) magnetic field.
This thesis intends to show the presence of non-dipolar component of the NS
magnetic fields as derived from a recent model by kebede[5]. We will derive both
the dipolar and non dipolar components of the field separately. We approach the
problem by applying Post-Newtonian approximation, to find the angle dependent
charge distribution on the surface of the neutron star, which results in the non dipolar
components of the NS magnetic field
