In the article, magnetization, viscosity and its increment (“magnetoviscous” effect) in a thin near-wall layer of the column of magnetic fluid that oscillates in the tube when applying a strong transverse magnetic field are assessed. Calculations were performed using formulae obtained on the basis of two different theoretical approaches. The described technique is of interest for studying magnetophoresis and the processes of aggregation of magnetic nanoparticles.
