In the present work, the numerical computation was carried out on the behavior of 5$\mu$m-sized particles in natural convection flow field and magnetic field. The results show that the 5$\mu$m-sized particles fall down along a certain trajectory in the magnetic field. If the natural convection flow field and magnetic field are applied simultaneously, the particles cluster at the vortex center or go along the fluid streak lines depending on the Ra number. Different coil locations produce various flow fields, which makes the bahavior of the particles different.
