The hamiltonian character of the perturbed magnetic field lines of a confined plasma let them be described by an area-preserving map. We use the fractal diagrams to analyse the destruction of the magnetic field lines of a Reversed Field configuration, when its magnetic configuration is described by a Generalized Standard Map. The fractal diagrams show that the dynamics of the magnetic surfaces is very dependent on the kind of magnetic perturbation, mainly on the number of modes of the perturbative spectrum.
