Abstract: Behaviors of a magnetic microchain which is an oscillating motion of micrometer-size magnetic particles’ cluster caused by an external magnetic field were investigated numerically. The hybrid simulation code which was based on the lattice Boltzmann method, the immersed boundary method and the discrete particle method was developed. The behaviors of a magnetic microchain depends on the number of magnetic particles in the magnetic microchain, frequency of external alternating magnetic field and the strength of applied magnetic field. Three types of behaviors, i.e., rigid rotational oscillation, rotational oscillation with deforming into S shape and splitting into several chains, depends on the number of magnetic particles.
Keywords: Magnetic microchain, magnetic particle, alternating magnetic field, numerical simulation
