Abstract
We study the effect of disorder and interactions on a recently proposed mag netic field induced localization mechanism. We show that both partially des troy the extreme confinement of the excitations occurring in the pure case and give rise to unusual behavior. We also point out the role of the edge s tates that allows for a propagation of the electrons in these systems.
