PURPOSE: Provided is a set of elements for assembling complex structures, the set comprising a plurality of first magnetic bar elements, having a first length, a plurality of ferromagnetic elements, and a plurality of second magnetic bar elements, having a second length. CONSTITUTION: The set of elements comprises a plurality of first magnetic bar elements(1), having a first length, a plurality of ferromagnetic elements(3), and a plurality of second magnetic bar elements, having a second length. The ferromagnetic elements(3) have a symmetric tridimensional shape, or a spherical shape. The second length of the second bar elements corresponds to the length of the diagonal of the square comprised of four first bar elements as sides, coupled each other in correspondence of the corners of the square by four electromagnetic elements.
