A problem of construction of the indestructible magnet with the characteristic magnetic induction of about 100 T has not been solved up to now notwithstanding efforts of many laboratories. Along with using of new strong materials and improving of the winding fabrication process it is promising to consider a possibility to construct a magnet with the quasi-force-free (QFF) winding. Previous study (see1-4, for example) has shown possibility to decrease significantly stresses in QFF magnet with the winding containing equilibrated current layers. In the basic part of the QFF magnet consisting of N layers, the residual pressure is N2 times less than the magnetic pressure of the generated field. The first full-scale model of the QFF winding 5'6 has demonstrated a possibility of its realization in a system with the face plate shields. The aim of calculations presented in the talk is to confirm on the concrete examples a possibility to achieve the megagauss field in the QFF magnet constructed from obtainable materials.
