The recent observations indicate that the presence of non-dipolar pulsars magnetic elds.rnPost-Newtonian approximation(PN) used in solving Einstein's eld equation in generalrnrelativity was made to derive the much more complicated non-dipolar pulsar magneticrnfield. In this work, we analyze the presence of non-dipolar components of the pulsarrnmagnetic field, as derived from a recent model by Kebede[5]. We will derive both therndipolar and non dipolar components of the field. We consider the quadrupole and octopolernfields, which result in the non dipolar components of the pulsar's magnetic field
