The results of numerical simulation of spontaneous magnetic field generation and influence of this field on laser produced plasma jet expansion in vacuum and low density gas are presented. The numerical simulation has been carried out using MAG code for the case of aluminum plate of 5 {mu}m of thickness irradiated by Nd laser. The laser pulse duration was 0.5 nsec at half-width, laser irradiation intensity was up to 10{sup 13} W/cm{sup 2} and laser focal spot diameter was about 100 {mu}m. According to the received results, the magnetic field amplitude achieves the value of 150 kGs. This fact has no considerable influence on the temperature maximum in laser produced plasma, but significantly affects the process of the energy transport from plasma jet to low density gas.
