Abstract
The results of mathematical simulation of electromagnetic and hydrodynamic processes, arising up in a liquid-metal aluminum conductor during passing of kiloampere single pulse current of the microsecond duration are presented. It is established that the compression of liquid conductor by magnetic pressure be- gins at exceeding of some threshold value of current strength in an pulse, determined by metal static pres- sure. The fields and absolute values of flow speeds are determined in an conductor depending on the parame- ters of pulse current.
