A study has been made of the regularities determining the electrophysical 
properties of magnetic fluids based on decane, turbine oil, water, and 
kerosene  as  functions  of  the frequency of  the  electric  field,  the 
concentration of the dispersed phase, and  the temperature.  The optimum 
frequencies of the electric field, concentration of  the dispersed phase, 
and temperatures within which the electrophysical characteristics,  such 
as the relative permittivity, the specific electrical  resistance,  and 
the  dielectric  loss  tangent,  turn  out to be the most informative for 
evaluation of the structure, compositions, and  properties  of  magnetic 
fluids have been determined.
