It is noted that when implementing the processes of magnetophoresis (one of the types of which is magnetic separation, used in various industries, including glass and ceramic), along with information about the fractional fraction of magnetoactive particles, information about their magnetic susceptibility is also fundamental. , depending on the strength of the applied field H. The data are given & # 967; for iron-containing particles-impurities of quartz sand, obtained from the results of measurements of the magnetic susceptibility of their powder samples. It is shown that the parameter & # 967;, being inversely dependent on H (with an exponent close to 0.75), significantly & # 171; suppresses & # 187; the role of the parameter H appearing in the basic expression for the magnetic force of particle capture. When creating magnetophoresis (separation) devices, it is recommended to pay increased attention not so much to the parameter H, as to the parameter characterizing the field inhomogeneity,? gradH, more responsible for the capture of particles
