Turbulent magnetohydrodynamic dynamo using the cross-helicity effect is applied to the interstellar or galactic magnetic fields. The strength of the interstellar magnetic fields estimated with the aid of the cross-helicity (velocity/magnetic field correlation) dynamo solution is in good agreement with the observed magnetic-field strength. Two typical configurations of the magnetic fields in galactic disks, which are bisymmetric and axisymmetric spiral fields, are elucidated by using the cross-helicity dynamo, and the configurations of the vertical magnetic fields are also discussed. Some implications about the stability of the turbulent cross-helicity configuration are presented with special emphasis on the role of the vertical magnetic field, the frozen-in field, and the jet from the galactic center.
