Abstract: The process of the two-step conversion of the neutrino helicity, $ u L \to u R \to u L$, is analysed in the supernova conditions, where the firststage is realized due to the interaction of the neutrino magnetic moment withthe plasma electrons and protons in the supernova core. The second stage iscaused by the neutrino resonant spin-flip in a magnetic field of the supernovaenvelope. Given the neutrino magnetic moment within the interval $10^{-13}\mu { m B} < \mu u < 10^{-12} \mu { m B}$, and with the existence of themagnetic field at the scale $\sim 10^{13}$ G between the neutrinosphere and theshock-wave stagnation region, it is shown that an additional energy of theorder of $10^{51}$ erg can be injected into this region during the typical timeof the shock-wave stagnation. This energy could be sufficient for stumulationof the damped shock wave.
