Popis: Using an averaging method to solve the differential field line equations, we present a simple procedure to determine analytically the main magnetic islands structure of toroidal tokamak plasmas perturbed by resonant helical windings. Analytical results are compared with Poincare maps: for small perturbations the sizes and the positions of the islands agree well, even for satellite islands.
