Research Abstract

Under the strong magnetic field, the motion of fine particles in a cylinder was numerically studied with the Langevin equation considering the Borwnian motion. The computed result was compared with the experimental one. In the experiment, water mist was generated and assumed as a Brownian particle. Accordingly, the density of a fine particle was set to equal to that of water at the numerical study. The experimental results showed that the water mist almost stops at some locations in the magnet at inclined angles, and this agreed well with the numerical results.
