Sách Effect of field strength in the velocity anisotropy of ferrofluids

Abstract: Ultrasonic velocity measurements were made on the starch coated magnetite particles in aqueous carrier under various external magnetic field strength. Density values are presented under no field condition and a few acoustical parameters were calculated. All the observations are interpreted in terms of grain-grain interaction and grain-field interaction that exist in the system. The field strength is found to enhance the structural formation in the system irrespective of its direction.
