Abstract
The recent observations and theory indicates that the presence of in nite non-dipolar
pulsars magnetic elds, it has become more and more clear that pulsars posses magnetic
eld structure, which are much more complicated than the simple assumption of dipolar
pulsars magnetic elds. In this work, we analyze the presence of in nite non-dipolar com-
ponents of the pulsar magnetic eld, as derived from a recent model. We derived both the
dipolar and in nite non-dipolar components of the eld separately. We have approached
the problem by applying post-Newtonian approximation, to nd the in nite non-dipolar
pulsar magnetic eld. Among in nite non-dipolar components of pulsar's magnetic eld,
we have both derived the expression for quadrapole and octupole component of the mag-
netic eld and studied their implication
