M.A. Volkov Re. At large distances cooling is more intensive and other factors such as inhomogeneous magnetospheric convection should be taken into account. Conclusions The precipitation of the charged particles 'effects the redistribution of plasma pressure and the Bz component of the magnetic field in the magnetosphere tail. This effect is manifested as the dipolarization o f the magnetic field lines. This effect, according to the results, is essential for a distance not exceeding 10 RE- At larger distances the cooling of magnetic tubes is difficult to explain only by precipitation o f the particles.
