A fully developed turbulent flow is capable to mix and homogenize
a suspension of heavy macroscopic particles even at a high
concentration of particles. If the particles are ferromagnetic, a
kind of “turbulent ferrofluid" can be obtained. In the present
work, we present a direct measurements of the
effective magnetic permeability in a turbulent
fluid with suspended ferromagnetic particles of typical size
0.01-0.1 mm and volume fraction c up to 25%. We show
that the effective permeability can be fitted by the linear law
for 
%. For higher volume
fractions the permeability exceeds this linear relation.
