[en] The generalized magnetic coordinates system, which describes magnetic fields with and without nested magnetic surfaces, is constructed for a simple analytic helical field involving magnetic islands. In order to analyze magnetic islands, the residue of a tangent map at the fixed points and the Fourier components of the perturbation of the magnetic field are studied. (author)
