A new mechanism of supernova shock revival is proposed which involves the resonant spin-flavor precession of neutrinos with a transition magnetic moment in the magnetic field of the supernova. The mechanism can be operative in supernovae for transition magnetic moments as small as 10{sup {minus}14}{mu}{sub B} provided the neutrino mass squared difference is in the range {Delta}m{sup 2}{approximately}(3 eV){sup 2}{minus}(600eV){sup 2}. It is shown that this mechanism can increase the neutrino-induced shock reheating energy by about 60{percent}. {copyright} {ital 1997} {ital The American Physical Society}
