Results of computer simulation of low-energy high-current electron beam generation in a low-impedance system
 show that high-current beams shape in paramagnetic states. Low-impedance system consists of a diode with a long
 plasma anode, just siding with an explosive emission cathode and an auxiliary thermionic cathode. The long plasma
 anode plays simultaneously the role of the transport channel providing charge neutralisation of high-current beam.
 Usually, a beam in an external magnetic field behaves as a diamagnetic and forces the magnetic field out of its volume.
 Earlier it was shown that for some systems it is possible to realise conditions under which the magnetic field is
 increased inside the volume occupied by the beam. It is accompanied by considerable increase of the magnetic field as
 compared as external field. The behaviour of beam-plasma system is discussed under different conditions. Computer
 simulation was performed using PIC code KARAT.
