Investigating the Structures of Paramagnetic Aggregates from Colloidal Emulsions-1

InSPACE-1 studied the response of MR fluids under continuous and pulsed magnetic fields in a microgravity environment. An objective was to determine the true three-dimensional low-energy (equilibrium) structure of an magneto-rheological (MR) emulsion in a pulsed magnetic field. InSPACE-1 aimed to conduct a microscopic video study of the MR fluid in a pulsed magnetic field to determine the effect of varying magnetic field, pulse frequency, and particle size on the equilibrium microstructures. A pulsed magnetic field is used to mimic the forces applied to these fluids in real applications, such as vibration damping systems. A pulsed field also tends to produce intricate, thick structures with different properties than structures produced by a constant magnetic field.
