Structural changes in water exposed to weak variable magnetic fields

Changes of dielectric loss, electrical conductivity, heat transfer coefficient, and supercooling are found in bidstilled water exposed to a weak variable magnetic field. The magnetic field affects charged protons, proton-containing groups in water, and their nuclear spins, inducing changes in the transition probabilities of these particles in the chains of the Bernal-Fowler hydrogen bonds. A prolonged exposure to the field results in structural changes of the hydrogen bond network. The newly-formed quasi-equilibrium macroscopic state of water takes a very long time (hours) to relax to the initial state.
