Abstract

We observed the phenomenon that water was parted by a magnetic field at 8 T. Two “water-walls” were formed and the surface of the water was parted. The bottom of the water chamber appeared when the water chamber was exposed to magnetic fields up to 8 T. This paper focuses on the mechanism of this phenomenon. The change in the lowest level of water was 22 mm when magnetic fields mere changed from 0 T to 8 T, and the decrease in water level was proportionate to B² at the center of the magnet. We also investigated the effect of temperature on the formation of the water-wall. We observed that the water-wall was formed at both 0°C and 100°C. Finally, we investigated the effect of mixed NaCl ions on the formation of the water-wall. The absolute change in water level declined as the concentration of NaCl rose
