Many physicochemical properties of water and water solutions change under magnetic fields exposure. These phenomena study is important for understanding the magnetic field effect on systems. The present work objective was to study the solvent properties of water under low frequency magnetic field in the specified frequencies range exposure and the solution density change after turning the magnetic field off. In virtue of the obtained results it can be concluded that under low intensity alternating magnetic field of 10 to 24 Hz frequency range exposure of distilled water used afterwards as a solvent of sulphate of copper, the Т value (average value difference of maximum emission transmittance depending on frequency of alternating magnetic field at the time of its transmission through exposed and unexposed to alternating magnetic fields water and test solution density compared to control solution), which gives evidence that water solvent properties increase. In case of distilled water exposed to low intensity alternating magnetic field with frequency range 1 to 10 Hz decrease of Т value and test solution density compared to those of control solution, which gives evidence that water solvent properties decrease. It was also shown that for prepared solutions the opposite effect of alternating magnetic field on the same frequencies. At 0 to 10 Hz range of alternating magnetic field the Т value and the density of test solution increased as compared to control solution with the raise of alternating magnetic field frequency, whereas at 10 to 24 Hz range monotone solvent properties and density decrease was observed with the raise of alternating magnetic field frequency up to saturation. The alternating magnetic field exposure effect to both water and prepared salt water solution was lost with time, the characteristics returned to initial state.
