Investigations to study the effect of magnetic field on water

摘要

Water is one of nature's most important gifts to mankind and is a key component in determining the quality of our lives. Many water purification systems have emerged in the market to satisfy the quest for good quality water for masses which no longer is a luxury but is a necessity. These all water purification systems boast of many quality advantages (like taste, odor etc) in treating water to destroy disease-producing contaminants that may be present in the water but without any enhancement in its chemical quality. Effect of magnetic fields on the properties of water and thus the use of water needed or desired for a better end result has attracted a great attention of masses. Magnetic field treatment of water for its improved thermophysical, thermodynamic and thermochemical parameters is a well advocated but less researched field. Similarly, ultrasonic velocity measurements through water can be used to calculate its various thermophysical and thermodynamic parameters and thus its suitable use can be ascertained. A combination of both, measurement of ultrasonic velocity through water is an important tool to study the influence of magnetic field and was thus investigated in the present study. 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 a 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., 1 MHz is selected, the ultrasonic velocity is different for different samples of water and increases in the order of Ordinary water (ODW)< Mineral water(MIW)
