This article investigates the geometric arrangement influence of external magnetic fields (Parallel and transverse magnetic fields with respect to laser beam propagation) on the laser rays propagation inside relativistic plasma. Adopting the nonparaxial theory of laser rays propagation, the results have showed that the increase of magnetic fields in both parallel and transverse regimes are leading to high self-focusing of laser beam. The parallel magnetic field alignment have illustrated a higher self-focusing, leading to higher intensity of laser beam inside plasma, comparing with transversal magnetic field.
