Abstract
A new model of electronic vortices in plasma is studied. The model ass umes that the profile of the Lagrangian invariant I, equal to the rati o I = Omega/n of the electronic vorticity to the electron density, is given. The proposed approach takes into account the magnetic Debye sca le r(B) similar or equal to B/4 pi en, which leads to breakdown of pla sma quasineutrality. It is shown that the Abrikosov singular model can not be used to describe electron vortices in plasmas because of the fu ndamental limitation on the electron vorticity on the axis of a vortex in a plasma. Analysis of the equations shows that in the model consid ered for the electronic vorticity, the total magnetic flux decreases w hen the size r(0) of the region in which I not equal 0 becomes less th an c/omega(pe) (omega(pe) is the electron plasma frequency). For omega (pe)r(0)/c much less than 1, an electronic vortex is formed in which t he magnetic flux decreases as r(0)(2) and the inertial component predo minates in the electronic vorticity. The structure arising as omega(pe )r(0)/c double right arrow 0 is a narrow ''hole'' in the electron dens ity, which can be identified from the spectrum of electromagnetic wave s in this region.
