Distance between a Vertical Solid Wall and a Falling Insulating Sphere in a Conductive Liquid under the Imposition of a Horizontal Static Magnetic Field

Abstract

For the clarification of falling behavior of an electrically insulating spherical second phase in the vicinity of a wall under the imposition of a horizontal static magnetic field, distance between the wall and a falling Polytetrafluoroethylene spherical ball in a saturated sodium chloride aqueous solution was observed under the imposition of the horizontal magnetic field where magnetic field intensity and its direction, and electrical conductivity of the wall were chosen as experimental parameters. The obtained distances were statistically analyzed. As the results, the distance when the horizontal magnetic field direction was parallel to the wall, and the distance when the wall was electrically insulating, were the same with the distance when the magnetic field was not imposed. On the other hand, the distance was smaller than the distance when the magnetic field direction was perpendicular to the electrically conductive wall.
