Preliminary results on a new Stretch‐Twist‐Fold (STF) kinematic model for fast dynamo are presented. The evolution is prescribed by equations that govern the simultaneous stretching, writhing and coiling of a magnetic flux‐tube by diffeomorphism of the initial circular configuration. Simple estimates based on minimized magnetic energy show that exponential growth of the magnetic field is indeed possible. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
