Аннотация:The field-aligned electron anisotropy is usually observed in the Earth’s magnetotail current sheet. This anisotropy is carried by subthermal electron population that may contribute significantly to the current density generation around the equatorial plane where magnetic field lines are very stretched and magnetic curvature radius drops to few hundreds km. In this presentation we discuss the simple 1D current sheet model that accounts for such field-aligned electron anisotropy. Using observed (not Maxwellian) electron energy distributions, we calculate electron currents generated by anisotropic electron population. This population forms quite narrow current layer around equatorial plane. We also compare theoretical estimates with the MMS observations.
