Title: Magnetic Relaxation, Helicity and Reconnection

The relaxation of magnetic fields in plasmas with high magnetic Reynolds numbers, such as the solar corona, is constrained by the total magnetic helicity. This constraint is at the heart of Taylor’s relaxation theory, which states that the relaxed state is one that minimises the energy while keeping the global helicity fixed. We will discuss the difficulties encountered in applying this theory to the solar corona and how concepts such as the field line helicity, as well as the unsigned helicity, can be used to better explain the results of numerical relaxation experiments.
