  The sterile neutrino mechanisms for natal neutron star kicks are reanalyzed.
It is shown that the magnetic field strengths needed for obtaining the
observable values of kicks were underestimated essentially. Another mechanism
with standard neutrinos is discussed where the outgoing neutrino flux in a
supernova explosion with a strong toroidal magnetic field generation causes the
field redistribution in "upper" and "lower" hemispheres of the supernova
envelope. The resulting magnetic field pressure asymmetry causes the pulsar
natal kick.
