FERROFLUID MENISCUS SHAPE IN AN APPLIED UNIFORM HORIZONTAL OR VERTICAL MAGNETIC FIELD

摘要

The classic Landau and Lifschitz analysis of the shape of a meniscus due to fluid wetting a vertical wall, including fluid weight and interfacial surface tension, is extended to ferrofluids stressed to magnetic saturation by a horizontal or vertical uniform magnetic field as shown in Figure 1. This analysis is the first step in a larger analysis to calculate the magnetic surface force due to ferrofluid surface shapes altered by magnetic fields and forces that cause surface driven flows in rotating magnetic fields.
