Neutrino in magnetic fields: from the first studies to the new effects   in neutrino oscillations
  In this paper I should like to present {\bf {{the four new effects}}} in neutrino oscillations that have been recently investigated in my research group at the Department of Theoretical Physics of the Moscow State University. Due to the fact that these studies were stimulated by our previous research of neutrino interactions in the presence of magnetic fields, and also because the year 2004 commemorates the 40th years jubilee since the the first paper on the neutrino interaction in a magnetic field was published, a short review on the first papers dedicated to the problem of neutrinos in magnetic fields, and also on the recent results in this field, prefaces (Section 1) the discussion on {\bf the new effects} in neutrino oscillations. Section 2 is devoted to our recent studies of the electromagnetic properties of a {\it massive} neutrino, including the neutrino magnetic moment for different values of neutrino mass. In Section 3 we discuss {\it \bf the four new effects} in neutrino spin and flavour oscillations in different background environments.
