Abstract
Today astronomical observations confirm that both radio Pulsars and Magnetars tend to be
found in the same locations of the Milky Way, in regions where stars have recently exploded as
supernovae.
The question has been: if they are located in similar places and are born in similar ways, then
why does a magnetar’s magnetic field decay in just 104 years, when a normal pulsar decays in
106 -107 years and why are magnetars (1014 -1015 Gauss) formed with stronger magnetic fields
than radio pulsars (1012 Gauss ).
In these work I will try to suggest possible answers for questions given above by
investigating the cause of the variation of the magnetic field and decaying time among neutron
stars. Moreover, I am also deriving an equation and stating an idea that describes the relation
between magnetic field and decaying time
