چکیده    In this paper we have studied the effect of magneto-static field on propagation of thermal wave generated in metal by pulsed laser. in fact this interaction generate acoustic wave in different mechanisms. however, always the common mechanism in the interactions of laser pulse and metal is the thermo-elastic wave generation. applying the suitable magneto-static field on the surface of interaction of laser pulse and metal can trap the propagation of thermal wave in thermo-elastic regime. the physical mechanism of trapping and experimental results have investigated in this paper. we obtained maximum reduction in 2d thermal wave propagation around in simulation and around 18 ±1% in simulation and around 5.3% by metallography.
