الملخص EN

The magnetic field ol pulsar (8).

is considered to be magnetic dipoic field.The pulsar- is a neutron star.

The pulsar magnetic field is about (10s T), with high curvature and radius of (104m).

The work is imerested on the geometry of the magnetic field within the light cylinder(RL=3* IOsm).Thc model of pulsar, which wc adopted, is that of (Goldriech & Julian), the dipole axis is in the same axis of the star rotation it is an aligned rotator.

Within this consideration we studied the types of gradient with changing position angle (A) The first tyoe.

-B-Gradient in (r) direction (V,.B), and the sccond type,-3-Gradient in (X) direction (VxB).The results indicated that the assumed magnetic field configuration enable us to estimate, why the two types of Grad.-B.

increase towards the limits of the light cylinder.Therefore wc noted the magnetic field inside the light cylinder is very strong with high curvature for star surface.

Also, we concluded, alter the boundary of (RL), the magnetic field lines are open and the charges will be accelerate with high velocity and flow out the light cylinder.
