[en] Experiments data are given on generation of a strong magnetic field by compressing magnetic flux with a conducting cylindrical liner accelerated under the effect of magnetic pressure (magnetodynamic cumulation). The magnetic field for the liner acceleration has been generated by a one-loop solenoid. The total power capacity of the battery for the solenoid pulse supply made Up 700 kJ. The liner is made of aluminium. The liner is 145 mm long, the wall thickness is 2 mm, external diameter is 108 mm, weight is 250 g. The initial magnetic field inside the liner (approximately 10 kGs) has been generated as a result of the 1.5x10^-2 F condenser battery discharge (190 kJ at 5 kV). Phases of aluminium liner collapse are shown. The liner kinetic energy acquired during acceleration reached 100 kJ. The experiments have shown a possibility of generating a strong magnetic field of the intensity over 10⁶ Gs as well as the magnetic field 100 times as strong
