Abstract

In this paper, we present the magnetic field of the collapsed core during a massive star supernova explosion, resulting from the conservation of magnetic flux, which forms a strong magnetic fields (B∽1013 G) Neutron stars. The vector potential from moving electric charge Q uniformly distributed over the surface of the spherical Neutron star of radius R and the multipole magnetic field have calculated. The interaction between the dipole magnetic field and multipole magnetic field lines takes place for Neutron stars; the dipole field is more dominantly than the interacting multipole magnetic field lines. We simulated the field line of dipole interaction with quadrupole, hexapole, octupole, etc.
