Magnetic forces are well-documented tools for positioning or controlling the relative motion of magnetic and nonmagnetic entities by magnetophoresis. Their action on soft matter is more subtle. There is a richness of possible static and dynamic behaviour, susceptible to the influence of magnetic fields, forces and torques. Furthermore, miniaturization offers new perspectives, driven by recent developments in nanomagnetism and microfluidics. It is therefore timely to discuss the new opportunities in interdisciplinary research that are arising at the interface between physics, chemistry, engineering, and life science.
Magnetic heterogeneity at a mesoscopic, micrometer to millimeter, scale and the key role of its time evolution require us to go beyond the well-established fields of ferrofluidics or magnetohydrodynamics. Novel magnetohydrodynamic concepts (new fluids and control), processes at interfaces (local probes, electrochemistry), applications of magnetic soft matter in cell biology, cargo transport and energy applications are a few examples.
This emergent field of magnetic microhydrodynamics requires an appropriate framework with dimensionless quantities to delineate its different regimes. This workshop is an opportunity to take stock of these recent developments, explore the science and build the foundations of a new research field
