Background The concept of magnetized water and the historically abbreviated glimpse were discussed. Therefore, the magnetic water treatment method has been summed up and considered a better and cleaner physical technique for water handling. This experimental work is focused on the effect of magnetic treatment on certain water parameters such as temperature, electrical conductivity (EC), total dissolved salts (TDS), and pH by exposing water to a permanent magnetic field (PMF) with a magnetic

... density (B = 1.45 T ± 0.05). Results This technique is realized by using a fixed system that depends on the application of both pump and valve control to induce the required circulation of employed water. Both open loop and closed loop are applied as a function of exposure time. Considering that the type of used water is brackish groundwater. The results showed that at open and closed flow conditions, the PMF causes variations in the values of the measured parameters for the outflow water. The theoretical approach is subjected to measure the molecular interaction of water system H-bonded systems based on DFT level with function B3LYP on Gaussian 09 software with a specific concentration of NaCl. This research focuses on the relation between the molecular structure of water and the dissolved NaCl with respect to applying a magnetic field with a varying force from 1 to 85 T. Conclusion The water's magnetization technique is simple without using extra energy by using a PWT tool to create a permanent magnetic field (B = 1.45 T ± 0.05) when installing it on a water tube system that was previously mounted. This environmentally friendly, renewable technology, therefore, does not need any additional energy requirements.
