【 摘 要 】

The article contains a brief description of the operation principles of the device for creating ultrafine metal powders under the action of electrically charged flows with a high power density. The results of creating a mathematical model of electromagnetic processes in the installation are presented. The results of solving the problem of current flow in the installation during its operation are presented. The dependence of the magnetic field strength in the section of the plasma bunch during the operation of the apparatus is illustrated.
