  • Abstract Numerous studies of magnetic fluctuations with a zero mean-field for small magnetic Prandtl numbers (Prm< 1) show that magnetic fluctu-ations cannot be generated by turbulent fluid flow with the Kolmogorov energy spectrum. In addition, the generation of magnetic fluctuations with a zero mean-field for Prm< 1 were not observed in numerical simulations. However, in astrophysical applications the magnetic Prandtl numbers are small and magnetic fluctuations are observed. Thus the mechanism of generation of magnetic …
