Abstract: We present 2D results of simulations of the magnetorotational core collapsed supernova. For the first time we obtain strong explosion for the core collapsed supernova. In 2D approximation we show that amplification of the toroidal magnetic field due to the differential rotation leads to the formation of a MHD shockwave, which produces a supernova explosion. The amount of ejected mass, 0.1MSolar, and energy, ∼ 0.5 ÷ 0.6 • 1051 ergs, can explain the energy output for supernova type II or type Ib/c explosions. The shape of the explosion is qualitatively dependent on the initial configuration of the magnetic field, and may form strong ejection near the equatorial plane, or produce mildly collimated jets. Our simulations show that during the evolution of the magnetic field the magnetorotational instability appears and leads to exponential growth of the magnetic field strength.
