Abstract
Preliminary results are reported for an experiment studying the dynamics of laminar magnetic vortex rings. These are formed through injection of a magnetic fluid (ferrofluid) into a nonmagnetic carrier liquid. An external magnetic field is used to strain the magnetic cores of the propagating rings without an additional external flow and away from solid boundaries. Varying field‐dependent growth rates and the development of field‐induced instabilities can be observed. Results are presented from an automated analysis of digitally recorded video sequences, resulting in time records of the evolving ring radii.
