  Results of 2D simulations of the magnetorotational mechanism of supernova
type II are presented. Amplification of toroidal magnetic field of the star due
to differential rotation of the star leads to the transformation of the
rotational (gravitational) energy to the energy of the supernova explosion. In
our simulation the energy of the explosion is $1.12 \cdot 10^{51}erg$. The
explosion ejects about $0.11 M_\odot$.
