Abstract

We systemically investigate the chain formation speed in magnetic fluid (MF) at various volume fractions, temperatures, and magnetic fields. Experiments are carried out on a water-based Fe 3 O 4 MF to investigate the agglomeration response of the nanoparticles under an applied magnetic field. The transmission of light is monitored to determine the response time undergoing a squared pulsed external magnetic field. The results reveal that enhancement of the response performance of photonic devices based on MF can be realized by properly adjusting the physical parameters, which are essential for both the phys ics of chain formation and practical applications.
