Investigations to Study the Effect of Magnetic Field on Water

摘要

In the present work, the impact of magnetic treatment on water microstructure using ultrasonic velocity measurements in the water samples (ordinary water, distilled water, mineral water and treated water) was investigated. The magnetic water treatment was used to examine the variation in ultrasonic velocity in water samples exposed to magnetic field of various strengths (200 - 800 gauss) in different materials containers (copper-a paramagnetic, aluminum-a diamagnetic and plastic) for a time period of 10 minutes which can further be used to evaluate the effect on the physicochemical properties (surface tension, viscosity etc) of water. It was found that exposure of magnetic field and type of container play significant role in the propagation of ultrasonic waves in the water and depends strongly on the type of water itself. If only single frequency i.e., I MHz is selected, the ultrasonic velocity is different for different samples of water and increases in the order of Ordinary water (ODW) ＜Mineralwater(MW) ＜Distilled water (DIW)＜ Filtered water (FIW). Filtered water (from RO) shows the maximum value of ultrasonic velocity for 1 MHz frequency ultrasonic waves.
