Scaling laws of turbulent dynamos
arXiv:physics/0701319 · doi:10.1016/j.crhy.2006.12.011
Abstract
We consider magnetic fields generated by homogeneous isotropic and parity invariant turbulent flows. We show that simple scaling laws for dynamo threshold, magnetic energy and Ohmic dissipation can be obtained depending on the value of the magnetic Prandtl number.
