Research Abstract

Water is diamagnetic though very weak. Then, if the magnetic field is applied to the surface of the water, it is pushed aside and forms the vertical walls due to the repulsive magnetic force. This phenomenon is named Moses' effect after the prophet Moses in the Old Testament. Utilizing this effect, the diamagnetic materials can be levitated and fixed in the specified position without direct contact. If the magnetic poles are long in the flow direction, the virtual flow channel can be formed and the fluid can flow through the virtual channel. This leads to the new technology of material processing without contamination and the new dosage method to concentrate the medicine only to the diseased part avoiding the side effects.
The fundamental principle depends on the weaker magnetization of the levitated fluid than that of the surrounding fluid, then the simulation even with the conventional weak magnets can be easily accomplished using the magnetic fluid as the surrounding fluid.
In the present research, a pair of long magnetic poles are set face to face each other to form the virtual channel, and the stability of the fluid column inside of the channel, the modes of the induced oscillation, propagation of the waves and instability of the surface are experimentally and analytically investigated.
