Abstract
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.Keywords
