Study on action forces on nano-particle to flat surface using localized remote magnetic field

2nd report: Magnetic Force Estimation for Attaching a Particle to SiC Substrate Surface by Applying Multi-Wave Evanescent Field

Abstract

Although magnetic nanoparticles are currently used as a method for precision polishing, localized processing is difficult due to the possible lack of control over magnetic nanoparticles. Therefore, in this study, the relationship between magnetic flux density and force was investigated by comparing the magnitude of magnetic force required for nanoparticles to attach to the substrate surface by simulation and experiment using a solenoid coil for localized control of magnetic nanoparticles.
