Magnetic manipulation of non-spherical magnetic microparticles is important for applications in shape-based and magnetic-based separations such as waste management, disease diagnostics, drug delivery, and mining. Manipulations of magnetic microparticles also include chain formation to assemble compositions for electronics, drug loading designs, and magnetorheological fluids for smart armor, hydraulic brakes, and dampers. In microfluidic devices, separation-formation-effectiveness depends on the shape of the channel, the shear rate, and the magnetic field strength and direction.Particle separation and chain formation involved highly complex and computational expense-demanding studies in microfluidic devices, magnetic fields, and particle-particle/wall interactions. This research took complex experimental studies and created simple theoretical and numerical studies for the dynamics of magnetic particles. The first study analyzed the rotational dynamics of paramagnetic and ferromagnetic particles in a simple shear flow and under a uniform magnetic field, as well as a numerical application in a Couette flow. In the second study, further theoretical analyses were derived for a three-dimensional rotation of both magnetic types. A paramagnetic particle was placed in a curved channel and under a uniform magnetic field in the third study. Finally, a two-dimensional investigation on the dynamics of two Janus particles under a uniform magnetic field and in a simple shear flow was the focus of the fourth study.In this research, the theoretical and numerical applications addressed how various magnetic types and particle shapes reacted in different magnetic field strengths, in addition to its directions, and under simple shear as well as channel flows. Among the following studies, micro-sized ellipsoidal and Janus particles demonstrated their rotation and migration behavior in straight channels, curved channels, and shear flows. The following studies support current and future studies in biomedical and industrial applications.
