Aggregation kinetics and macroscopic properties of athermal suspension in uniaxial magnetic field

The aggregation kinetics in a magnetic fluid emulsion as a model system under the action of an external uniform stationary magnetic field is studied experimentally. The process of structure formation is analyzed by measuring the macroscopic magnetic permeability of a three-dimensional sample of the...

description	The aggregation kinetics in a magnetic fluid emulsion as a model system under the action of an external uniform stationary magnetic field is studied experimentally. The process of structure formation is analyzed by measuring the macroscopic magnetic permeability of a three-dimensional sample of the emulsion. This makes it possible to obtain information on the aggregation kinetics in an athermal polydisperse unbounded suspension.
