Micro-visualization and PTV analysis on ferromagnetic particles behavior

Abstract

Thermal behavior and cluster formation of ferromagnetic particles in magnetic fluids were investigated using an optical microscope system and PTV image data processing system. Real-time visualization of the Brownian motion and the chain-like cluster formation of three types of particles were carried out under a magnetic field. The influence of the magnetic field intensity and the temperature variation on cluster formation of ferromagnetic particles was investigated.
