Abstract: | Urca neutrino reemission processes under the conditions in the mantle of a supernova with a strong toroidal magnetic field
are investigated. It is shown that P-parity violation in these processes can be manifested macroscopically as a torque that
rapidly spins up the region of the mantle occupied by such a field. Neutrino spin-up of the mantle can strongly affect the
mechanism of further generation of the toroidal field, specifically, it can enhance the field in a small neighborhood of the
rigid-body-rotating core of the progenitor star.
