  Results of 2D numerical simulation of magnetorotational mechanism of
supernova explosion are presented. It is shown that due to the differential
rotation of the star toroidal component of magnetic field appears and grows
with time. Angular momentum transfers outwards by the toroidal magnetic field.
With the evolution of the process part of the envelope of the star is throwing
away. The amount of thrown away mass and energy are estimated. The results of
the simulation are qualitatively correspond to supernova explosion picture.
