Abstract: We study the two-dimensional interacting electrons in magnetic field. It is found that for systems with completely filled Landau levels, when the electron density and magnetic field are large enough, the total energy is lowered by magnetic field. The exchange Coulomb interaction is responsible for such a transition.
