Аннотация:We consider analytically and with MHD simulations the regimes of driven magnetic field line
reconnection in two planar magnetic configurations with two null lines (X-lines), with boundary
conditions that correspond to the excitation of the finite amplitude magnetoacoustic and Alfv6n waves.
We demonstrate that the change of the magnetic field topology due to the magnetoacoustic type
perturbations is accompanied by the global redistribution of the electric current curried by the Alfv6n
waves
