Chaotic Flows and Magnetic Dynamos

Phys. Rev. Lett. 60, 760 (1988)https://ireap.umd.edu/10.1103/PhysRevLett.60.7601988Journal ArticleComplex and Emergent Systems

Examples of time-dependent kinematic magnetic dynamos arising from chaotic flows in the zero-resistivity limit are presented. These examples suggest that typically (1) the flux concentrates on a fractal, and (2) the magnetic field exhibits arbitrarily fine-scaled oscillations between parallel and antiparallel directions. Results quantitatively relating these effects to the dynamo growth rate are presented.
