The mechanism for magnetic field generation in hybrid neutron stars (containing “npe,” hadron, “2SC” and “CFL” quark phases) is discussed. It is assumed that the rotational vortices in “npe” and “CFL” phases with a quantum of circulation h/2m also continue in the “2SC” phase. Since the superconducting components in the “npe” and “2SC” phases are charged, entrainment currents develop around the vortices and generate a magnetic field. The average magnetic field in the quark phase is on the order of 5·1015 G and exceeds the field in the “npe” phase by 2-3 orders of magnitude. The magnetic field penetrates into the “CFL” phase by means of magnetic vortices with a flux 2Φ0 and it can partially destroy the proton superconductivity in the “npe” phase. On the star’s surface, the magnetic field reaches 5·1014 G, a level comparable to the magnetic field of magnetars. Magnetars may, therefore, contain quark matter.
