Abstract
The paper gives an assessment of the viscosity increment (magnetoviscous effect) in a thin near-wall layer of a column of magnetic fluid which oscillates in a tube when applying a strong transverse magnetic field. The value of the magnetoviscous effect was calculated using a formula derived from two different theoretical approaches and applied to previously published experimental results of complex measurements of the oscillation frequency and saturation magnetization of a magnetic fluid under the assumption that there is no viscosity field dependence.
