Magneto-optical properties of water and saltwater in presence of a magnetic field

Abstract

The magneto-optical (transmittance, absorbance, and reflectance) characteristics of water and saltwater in the presence of a magnetic field (0T to 0.880T) are investigated in this study. The authors studies Raman spectra shift and a magneto-optical response of water and saltwater in magnetic fields. In the case of water, the transmittance is high in a high magnetic field, but in the case of saltwater, the transmittance is low at the low wavelength of the spectrum. The transmittance of water was found to be 0.7 percent higher in the presence of a high magnetic field of 0.88T than in the absence of a magnetic field at the wavelength of 651nm–655.67nm. Similarly, under the same magnetic field (0.88T), transmittance of seawater was found to be 0.9 percent higher at 401.44nm and absorbance was found to be 3.4 percent higher at 622.72nm and 646nm. High magnetic fields, on the other hand, have higher absorbance and reflectance in saltwater than 0.222T and 0T. The MO response was found to be larger in water at 0.880T than in saltwater at 0.222T. At 0.880T, the maximal MO response of water and saltwater is reported to be 0.004983 and 0.009804, respectively, at wavelengths of 668.2 nm and 400 nm. When compared to 0T, the intensity ratio of water is deflected more in a high magnetic field than in a low magnetic field, whereas the intensity ratio of saltwater is deflected less in a high magnetic field than in non-magnetic and low magnetic fields.
