Abstract
We discuss the selfsimilar solutions of MHD equations, when the Hall's effect is incorporated into the Ohm's law. These solutions describe current sheet formation in the vicinities of magnetic field zero points, zero lines and separatrix surfaces. We present the results of computer simulations of 2(1/2)D —MHD flows near the X- line of the magnetic field. We demonstrate that the Hall's effect makes the zero points to shift into the direction of electron component motion and leads to magnetic island formation.
