The effects of magnetic fields on water molecular hydrogen bonds

In this paper, the experimental results on the effects of a magnetic field on water are reported Purified water was circulated at a constant flow rate in a magnetic field After this treatment, the physicochemical properties of water were changed, shown as the decrease of surface tension and the increase of viscosity over the treatment time. The water is more stable by magnetic treatment with less molecular energy and more activation energy. as shown from the calculation based on the results. The correlation time tau(c) was calculated in terms of spin-lattice relaxation time of proton NMR. which verified that the rotational motions got slow down after magnetic treatments. A two-phase model was set up to prove that the proportion of free water molecules was reduced The results suggested that the average size of water clusters became larger by magnetic treatments.
