An approach to designing quasi-force-free configurations of non-destructive magnets aimed at achieving pulsed megagauss fields above 100 T is presented. Axisymmetric configurations of magnets that are characterized by a low ratio of the mechanical stresses in the windings to the magnetic pressure of the generated field are presented. The characteristic feature of new variable-radius configurations is the reduced magnetic field in the area close to the coil end, which allows to overcome limitations caused by mechanical stresses in the end area. Further development of this approach may lead to megagass-level research magnets.
