Determining the Magnetic Susceptibility of Ferroparticles from the Susceptibility of Their Dispersive Samples

摘要

Experimental data of the magnetic susceptibility of dispersive media in a magnetic field of intensity 90-780 kA/m is provided. For the required limitation of the volume fraction of ferroparticles, gamma <= 0.02-0.05, the field dependences of the magnetic susceptibility of individual particles and their material (magnetite) are obtained. The possibility of solving similar problems with less rigid limitations on the volume fraction of ferroparticles is substantiated.
