1539 磁場による磁性流体界面の不安定性

抄録

An experimental investigation has been made on the breakdown and spacing of magnetic fluid droplets by a vertically oriented magnetic field. When no magnetic field exists, a magnetic fluid droplet lying in a vertical gravitational field on a horizontal plane takes an equilibrium shape. When a vertical magnetic field is applied and its intensity increases, the droplet extends vertically. If the magnetic field intensity exceeds a critical value, the droplet breaks down into two droplets. We show these phenomena experimentally and compare with the surface phenomena of a magnetic fluid pool.
