    Research output: Contribution to journalArticlepeer-review


    Generation of magnetic field energy, without mean field generation, is studied. Isotropic mirror-symmetric turbulence of a conducting fluid amplifies the energy of small-scale magnetic perturbations if the magnetic Reynolds number is high, and the dimensionality of space d satisfies 2.103 < d < 8.765. The result does not depend on the model of turbulence, incompressibility, and isotropy being the only requirements.
