In the report the dynamics of the Toroidal Plasmoids formation in a Cavity of the Neck (TPCN) of plasma columns and tubes is described. The study was carried out within the MHD (magnetohydrodynamics) frames and by using the particles method. It was shown that in the fast forming neck of plasma pinch, some observed orthogonal to the current structures could be H-filaments (at the equilibrium state they are q-pinches). These filaments are supported due to the interaction of the induced (secondary) current with magnetic field of the Z-pinch.
