Abstract :
The formation of compact magnetic structures by advection of an initial magnetic seed due to the motion of the plasma, and the intensification of the field due to line stretching are discussed. It is shown that when the plasma is squeezed locally by external agents, so that an inflow-outflow near a stagnation point is generated by the pinching, large amounts of Joule heating are obtained in a short time when the magnetic Reynolds number is large
