磁気力ーテンにおけるガス流のシミュレーション

抄録

  We have observed a phenomenon that flows of gases such as carbon dioxide and oxygen are blocked by magnetic fields. A model called a “magnetic curtain” has been introduced to explain this phenomenon. It is assumed that the magnetic curtain is a wall of air which is made by magnetic fields. In this study, we simulated flows of gases in gradient magnetic fields, introducing a model based upon molecular dynamics. It is assumed that gas molecules such as nitrogen and oxygen are particles, and further assumed that those particles move in a two dimensional space. Paramagnetic oxygen is accelerated by magnetic force determined by the product of magnetic field and the gradient. We simulated trajectories of gas flow in gradient magnetic fields at various maximal magnetic forces (f_max). With nitrogen gas, gas flow is clearly disturbed at f_max=10^-15 N. However, in the experiment the blocking of gas flow is observed at f_max= 10^-23 N. This difference may be explained by the interaction between magnetic fields and mass behavior of particles as a group.
