Investigation of the effect of magnetic field on some physical properties of water

الملخص EN

The main purpose of this study was to investigate whether or not a water treatment by magnetic field could change the physical properties of water as reported in some scientific literature, the properties which were studied such as density, electrical conductivity, total dissolved solids, pH value, and NaCl concentration.

The water sample which tested in this study was well water, the magnetically treatment of well water samples was by two types of magnets; first type was electromagnet of low fixed intensity (900 G=90mT), where the water samples were exposed to this magnetic field at various times (5, 10, 15, 20, 25, 30) min.

The second type was permanent magnet, the exposing time to permanent magnetic field was 7 days.

It was found that these examined physical properties of well water samples were changed following the magnetic treatment, the changes depend on the magnetization conditions, and the magnetic field causes changing in the electrical conductivity due to the ability to dissolve and dissociate salts; influence on solubility of salts was remarkable.

As well as a positive effect on the pH value, the water samples become less acidic.

The results of this study suggested that the magnetic treatment improve quality of water, therefore, the magnetization process submits improvements on water applications in several areas such as industry, agriculture and medicine.
