The properties of water and their changes under the action of a magnetic field were gathered by the spectrum techniques of infrared, Raman, visible, ultraviolet and X-ray lights, which may give an insight into molecular and atomic structures of water. It was found that some properties of water were changed, and a lot of new and strange phenomena were discovered after magnetization. Magnetized water really has magnetism, which has been verified by a peak shift of X-ray diffraction of magnetized water + Fe 3 O 4 hybrid relative to that of pure water + Fe 3 O 4 hybrid, that is a saturation and memory effect. The properties of infrared and ultraviolet absorptions, Raman scattering and X-ray diffraction of magnetized water were greatly changed relative to those of pure water; their strengths of peaks were all increased, the frequencies of some peaks did also shift, and some new peaks, for example, at 5198, 8050 and 9340 cm −1 , occurred at 25℃ after water was magnetized. In the meanwhile, the magnetized effects of water are related to the magnetized time, the intensity of an externally applied magnetic field, and the temperature of water, but they are not a linear relationship. The study also showed a lot of new and unusual properties of magnetized water, for example, the six peaks in 3000-3800 cm −1 in infrared absorption, the exponential increase of ultraviolet absorption of wave with the decreasing wavelength of light of 200-300 nm, the frequency-shifts of peaks, a strange irreversible effect in the increasing and decreasing processes, as well as a stronger peak of absorption occurring at 50℃, 70℃ and 80℃, the existence of many models of motion from 85℃ to 95℃ in 8000-10000 cm −1 , and so on. These results show that the molecular structure of water is very complicated, which needs further study. Furthermore, the macroscopic feature of mechanics, for instance, surface tension force of magnetized water, was also measured. Experiments discovered that the size in contact angles of magnetized water on the surface of hydrophobic materials decreases, thus the surface tension force of magnetized water decreases relative to that of pure water. It is seen from the above results that the clustering structure of hydrogen-bonded chains and polarization effects of water

Effects of static magnetic field on optic properties of water are investigated by infrared spectroscopy, ultraviolet spectroscopy and X-ray diffraction, respectively. The ultraviolet spectroscopy experiments show the changes of properties of water under action of static magnetic field, in the region of 191 to 400 nm. The infrared experiment shows that the water exposed in a magnetic field had saturation and memory effects. The magnetized effects increased with increasing exposed time, but were weakened with increasing of time when the magnetic field was removed. In the X-ray experiment, the strength of diffraction increased also, after the water was exposed in magnetic field. Meanwhile, the shift of peak and increase of strength of X-ray diffraction of magnetized water added with nanoFe 3 O 4 occurred as compared with that of pure water added with nano Fe 3 O 4. This result suggests that the magnetized water has certain magnetism. Finally, these phenomena are simply explained by the molecular structure of water and the theory of magnetization of water.water, infrared spectroscopy, ultraviolet spectroscopy, X-ray diffraction, static magnetic field As are known, water is the most important matter on the earth and relates closely to the growth and development of human beings, animals and plant. Therefore, it is the basis of life. However, some features of water have not been clearly known up to now. The change of properties of water under action of magnetic field is just a typical case. From the 1950s, we have known that [1,2] water can be magnetized when exposed in a magnetic field, although the effect is very small. Experiments show that a lot of properties of magnetized water such as dielectric constant, refractive index, volatility and surface tension are changed as compared with that of pure water [3][4][5][6][7] . The magnetized water can be used to remove dirty [8][9][10] . But by now, there is still no systemic study on the mechanism and features of magnetization of water, so the understanding about the essence of magnetization of water is ambiguous, but some relevant study is helpful to investigating this issue. For example, He and Liu [11] investigated the nonlinear magnetization dynamics in a ferromagnetic nanowire with spin current, and Licinio et al. [12] investigated the nonlinear dielectric response of ferrofluids under action of magnetic field. Besides, Ozeki et al. [13] investigated the absorption of water on solid surface under action of magnetic field. In ref.[14], Chang et al. used molecular dynamics simulation to investigate the changes of structure of water under action of magnetic field. Recently, Pang [15] thought the effect of magnetic field on water is a non-linear problem and proposed the mechanism of magnetization of water according to the structure of water molecules. In such a case, it is very necessary to study in detail the properties and features of magnetized water for revealing the essence and mechanism of magnetization of water. Because water molecules can interact with lights wi...

The influences of magnetic field on thermodynamic, mechanical and electromagnetic properties of water including the specific heat, surface tension force, soaking effect or angle of contact, refraction index and electric conductivity are studied. From these investigations we know that the magnetic fields reduce the specific heat of water, increase the soaking degree and hydrophobicity of water to materials, depress its surface tension force and increase refractive index and electric conductivity of water relative to those of pure water. We can predict that these changes are caused by the changes of microscopic structures and distribution of water molecules under the action of a magnetic field. Therefore, our studies have important significations in science and has practical value of application of magnetized water.
