In this talk we discuss the stability properties for a family of equations introduced by Moffatt to model magnetic relaxation. These models preserve the topology of magnetic streamlines, contain a cubic nonlinearity, and yet have a favorable L^2 energy structure. We address the local and global in time well-posedness of these models and establish a difference in the long time behavior of solutions with respect to weak and strong norms. Based on joint work with Susan Friedlander and Vlad Vicol.
