Краткий осмотр (реферат): The properties of Hall drift of electrons and generation of respective self magnetic field are examined. The problem of design of high effective cryogenic generator of magnetic field advances the requirement of optimization of magnetic system geometry for the most magnitude of field to be obtained in the same volume at the same energy supply. Besides an electron drift along electric field there is a transverse drift of carriers stimulated by Lorentz force if magnetic field is applied. Generally transverse Hall drift as a source of magnetic field is ignored. A paper is represented here to indicate a novel way of improvement of magnetic system arrangement and efficiency. It is based on validity of use the energy concentrator made from high purity aluminum. Such concentrator may be installed into traditional solenoid and as a consequence the magnitude of magnetic field will increase. An experiment on A1 disk conductors having inner and outer concentric current leads is made in coaxial magnetic field of 8T. Current density is sufficient to achieve a boiling crisis of helium. It is shown that magnetic field of solenoid will be increased in volume of concentrator in accordance with power type law instead of summation taking place in many layer solenoid system. The benefits and advantages of application of magnetic field of Hall drift arc discussed. Parameters together with all necessary requirement for operation are represented for cryogenic range of temperature 4.2–30 K. Research is supported by Fund of Fundamental Investigations of the Republic of Belarus.
