Abstract
We study the magnetic field fluctuations generated by a turbulent swirling flow in the presence of an externally applied magnetic field. We show that the spectra of local magnetic field fluctuations have a region of power law scaling which is interpreted in terms of Kolmogorov's model of turbulent v elocity fluctuations. We also discuss the mean and rms values of the magnet ic field induced by the velocity gradients. [S1063-651X(98)08312-3].
