The Generation of Magnetic Fields through Driven Turbulence

We have tested the ability of driven turbulence to generate magnetic field structure from a weak uniform field using three-dimensional numerical simulations of incompressible turbulence. We used a pseudospectral code with a numerical resolution of up to 1443 collocation points. We find that the magnetic fields are amplified through field line stretching at a rate proportional to the difference between the velocity and the magnetic field …
