Transitions in a system of neutrinos with vacuum mixing and magnetic moments propagating in matter and a transverse magnetic field are considered. It is shown that in the realistic case of a magnetic field direction varying along the neutrino path qualitatively new phenomena become possible: the permutation of neutrino conversion resonances, appearance of resonances in the neutrino-antineutrino ([nu][sub [ital l][ital L]][leftrightarrow][bar [nu]][sub [ital l][ital R]]) transition channels, neutrino-antineutrino resonant conversion, large amplitude [nu][sub [ital l][ital L]][leftrightarrow][bar [nu]][sub [ital l][ital R]] oscillations, merging of different resonances (triple resonances). The possible phenomenological implications of these effects are briefly discussed.
