METHOD FOR PULSED MAGNET FIELD GENERATION (VERSIONS) Russian patent published in 2009 - IPC H02N11/00 

FIELD: electricity.

SUBSTANCE: method is intended to be used in electric engineering and electronics, for instance, in devices for high-power short current pulses generation. The method includes installation of hollow cylinder made of metal with low electrical conductivity in solenoid cavity, creation of initial magnet field by current transfer through solenoid winding, infusion of initial magnet field into cylinder chamber by diffusion technique, magnet field compression by cylinder walls moving along the chamber axis. In this case hollow cylinder is forced to rotate around its axis at the moment of magnet field compression, or hollow cylinder is made of flat or tube stock material by rotary drawing method (rolling-off) and drawing is performed in one or several stages while stock is rotated in one direction, or hollow cylinder is made of flat or tube stock material by rotary drawing method (rolling-off) in one or several stages and cylinder stock material is rotated in direction coinciding with direction of cylinder rotation at the moment of magnet field compression.

EFFECT: pulsed magnet field properties improvement by suppression of instability of cylinder inner surface shape during its squeesing.
