Abstract
We have investigated a relativistic jet injected into an oblique magnetic field in a slab geometry using a newly developed relativistic magnetohydrodynamic simulation code. The simulation code employs a simplified total variation diminishing method. We compare the nonrelativistic and relativistic jets to find the relativistic effects when the jet propagates across the oblique magnetic field. Numerical results show that both the nonrelativistic and relativistic jets are bent by the oblique magnetic field. However, the relativistic jet is weakly bent compared to the nonrelativistic one. We try to express the bending scale detected in the simulation with a simple model and find good agreement between them. We apply the results to the explanation of the bending of the extragalactic jets.
