Effect of magnetic field on optical features of water and KCl solutions

Water and KCl solutions were exposed to four different magnetic fields for 20 min respectively. Influences of magnetic field on microscopic structures and macroscopic properties of water and KCl solutions were studied by FTIR and the continuous spectrum techniques of linearly polarized light in ultraviolet, visible and near-infrared areas. Simultaneously, these quantities were determined for unmagnetized samples, as references. It was found that in the UV–vis area, the transmittance of all samples presented different phenomena when the incident light with different polarized, it resulted from the orientation of water molecules affected by the static magnetic field and the spiral motion of ions in the magnetic field. The IR spectrum showed that KCl had a significant structure-breaking effect when the intensity of the magnetic field increased and the absorption in the spectrum of KCl was a reflection of the perturbations that water bore in the presence of K+ and Cl− ions.
