Numerical simulations on the behavior of a red blood cell (RBC) suspended in a stationary fluid and parallel flow under steady uniform magnetic field were carried out in this study. Finite element method (FEM) and spring model were used to calculate the RBC membrane, and finite volume method was used to solve the flow field. These calculations were coupled by using the immersed boundary method. The magnetic effect on the RBC was model by considering the anisotropic diamagnetic susceptibility of the membrane components. The torque produced at each edge components was first calculated, and then the force applied to each node was evaluated. In the stationary fluid case, the RBC oriented so that the concave surface aligned parallel to the magnetic field, which corresponded to the experimental results. In the parallel flow case, the RBC oriented and remained steady due to the balance between the forces of the shear flow and magnetic field. In this case, a correlation between the inclination angle and magnetic field intensity was observed.
