The efficiency of using a diamagnetic screen with inertial retention in a non-destructivequasi-force-free magnet of a small volume (with a characteristic dimension about 10 cm^3 ) forgenerating a superstrong magnetic field with a pulse duration of about 10 µs is shown. Aconfiguration of the magnet was developed, in which the end part of the winding is balanced dueto the fact that the screen virtually does not move during the discharge. Mechanical stresses inthe winding were calculated, and it was demonstrated that mechanical strength of the windingcan be ensured in a field with magnetic flux density up to 100T. Calculations of the heating ofthe winding were performed and the possibilities of its reduction to an acceptable level areindicated.
