The influence of the viscosity on the oscillations of the element of magnetic fluid in the magnetic field

Abstract

The article describes a study of the viscoelastic parameters of the system based on a element of magnetic fluid bounded by the surface of a horizontal plexiglass tube located in the field of an electromagnet. A element of magnetic fluid makes damped oscillations. A mechanism is proposed for interpreting the experimental results to determine the dependence of the viscosity of a magnetic fluid on the magnetic field strength.

The Force on a Magneto-spherical Particle Oscillating in a viscous Fluid Perpendicular to an Impermeable Planar Wall with Slippage

“…Moreover, Polunin et al [24] expanded the physical understanding of the oscillating flow of magnetic fluid in the magnetic field by studying the effect in the thin near-wall layer under a strong transverse magnetic field. Therefore, Ryapolov et al [25] described a study of the viscoelastic parameters of the system based on an element of magnetic fluid bounded by the surface of a horizontal plexiglass tube located in the field of an electromagnet that makes damped oscillation. Üstündag et al [26] used the keyhole during high-power laser beam welding in partial penetration mode by means of a high-speed camera where an oscillating magnetic field was applied perpendicular to the welding direction on the root site of the steel plate.…”
