Magnetic fluids are suspension of ferromagnetic particles less than 10nm in diameter and it is well-known for the chain(cluster) formation of the magnetic particles under the magnetic field. In the present paper, using the light scattering from the particles, direct visualization on the behavior of cluster formation of the ferromagnetic particle and non-magnetic particles have been made under the magnetic field.
