The transverse component of the solar magnetic field may change its direction along the path of neutrinos. We examine possible consequences of such a twisting magnetic field in the proposed Sudbury Neutrino Observatory and BOREXINO experiments. Although for certain magnetic field configurations twisting can give rise to the production of electron antineutrinos, we show that such a process is sensitive to the detailed structure of the magnetic field.
