   Sammanfattning : The main idea behind the work presented in this thesis is to investigate if it is possible to find a mechanism that leads to surface magnetic field concentrations and could operate under solar conditions without postulating the presence of magnetic flux tubes rising from the bottom of the convection zone, a commonly used yet physically problematic approach.In this context we study the ‘negative effective magnetic pressure effect’: it was pointed out in earlier work (Kleeorin et al.
