How a rotating magnetic field causes ferrofluid to rotate

Mark Shliomis

Summary: The article investigates the mechanisms by which a rotating magnetic field causes a magnetic fluid to rotate in a cylinder, known as the spin-up of ferrofluids. The traditional theory of spin diffusion cannot explain this phenomenon due to low spin viscosity. A new theory linking the rotation of a free surface layer to the shape of the meniscus is developed, along with an analysis of the volumetric flow mechanism and the impact of natural convection on the flow.
