“…The present work lies at the intersection of two fields: the draining of films and ferrofluids. To our knowledge, the paper by Elias et al [9], the present paper, and a companion paper which analyzes the model we derive here [14], are the only studies of this type. As mentioned above, one benefit of exploring this area is to better understand the process of a draining film.…”

“…In different studies, they used this idea to investigate the properties of magnetic cells [10] and foams [11]. More relevant to the present study, in one set of experiments [9] they subjected a vertical film draining into a bath to a uniform magnetic field, and found that they could speed up or slow down the draining process based on the orientation of the magnetic field. In this paper, we explore a similar experimental setup, but with a key difference: we place strong magnets above an isolated film, thus achieving much stronger and non-uniform magnetic fields.…”

“…One way to understand the physical properties of soap films is to add a controllable component to the system. This idea has been explored by Elias et al [9], who added an aqueous suspension of magnetic nanoparticles to an ordinary soap solution, thus forming a magnetic soap solution. In other words, they replaced the continuous liquid phase of the soap solution with a ferrofluid, or magnetic liquid.…”

We investigate the draining of a vertical magnetic soap film in the presence of a strong, nonuniform magnetic field. A colloidal suspension of magnetic nanoparticles in a regular soap solution yields a magnetic soap solution, from which a soap film is formed across an isolated frame. Experiments demonstrate that with a strong magnet placed above the frame, the film may be made to flow upward against gravity. The amount of film draining upward is altered by varying the distance between the frame and magnet. A first mathematical model is developed for the evolution of the film. Simulations demonstrate qualitative agreement with the experiment.

“…In [9], Elias et al explored the physical properties of soap films by adding an aqueous suspension of magnetic nanoparticles to an ordinary soap solution, thus forming a magnetic soap solution. This added magnetic dimension was treated as a macroscopic force which they could control by subjecting the film to varying magnetic fields.…”

A colloid comprises a collection of small particles, droplets, or bubbles of one phase having at least one dimension between about 1 and 1000 nm and dispersed in a second phase. Either or both phases may be in gas, liquid, solid, or supercritical phase states. Another property that distinguishes colloidal dispersions is the extremely large area of the interface between the two phases compared with the mass of the dispersed phase. A consequence is that any chemical and physical phenomena that depend on the existence of an interface become very prominent in colloidal dispersions. Colloidal systems are important because they feature prominently, in both desirable and undesirable contexts, in a wide variety of practical disciplines, products, and industrial processes. The field of colloids also overlaps heavily with the field of nanotechnology. The problems associated with colloids are usually interdisciplinary in nature, and a broad scientific base is required to understand them completely. This article provides an introduction to the field of colloids, emphasizing the wide range of practical and industrial applications.
