Motion of a deformable drop of magnetic fluid on a solid surface in a rotating magnetic field

TL;DR

This study experimentally investigates how a magnetic fluid drop deforms and moves on a solid surface under a low-frequency rotating magnetic field, measuring its shape changes and translation velocity.

Contribution

It provides new experimental data on the deformation and motion of magnetic fluid drops under rotating magnetic fields, highlighting their dynamic behavior.

Findings

Drop shape deformation observed under rotating magnetic field

Measured translation velocity varies with field amplitude and frequency

Identified relationship between magnetic field parameters and drop motion

Abstract

The behavior of a magnetic fluid drop lying on a solid horizontal surface and surrounded by a nonmagnetic liquid under the action of a uniform magnetic field which is rotating in a vertical plane with low frequency (of the order of 1 Hz) has been investigated experimentally. Shape deformation and translatory motion of the drop were observed and studied. The drop translation velocity for different field amplitudes and field frequencies has been measured.
