The effect of static magnetic field on the biophysical properties of
distilled water is investigated in this work. Magnetic field was applied in a
direction perpendicular to distilled water drops coming from a burette (drop by
drop), using a variable gap magnet, producing a magnetic field of strength
varying from 0.2 up to 5 kG. Variations in the rate of flow of water, electric
conductivity and dielectric constant were observed. Increasing the strength of
magnetic field decreases the rate of flow, increasing both the electric
conductivity and the dielectric constant of water.

1. Introduction:
Water is an unusual substance, mostly due to its 3D network of
hydrogen bond in the molecule. Its properties allow it to act as a solvent, as a
reactant, as a molecule with a cohesive properties, as an environment and as a
temperature stabilizer. It has relatively high melting and boiling points for a
small molecule, high specific heat capacity, and higher density of liquid than
that of solid [1]. Because of water’s strong hydrostatic forces water is
incompressible, a property that allows cells filled with water to become turgid.
Enhancement of the formation of hydrogen bonds in water molecules under
high pressure was reported [2]. These unique properties of water make it
perhaps the most biologically important substance. In living organisms, water is
essential to solubilize and modify the properties of biomolecules such as nucleic
acids, proteins and carbohydrates by forming hydrogen bonds with their polar
functional groups [3].

Water is diamagnetic, however, its biophysical properties can be
affected by magnetic field [4, 5]. Nakagawa et al. [6] observed magneto
enhancement of water vaporization rate and attributed this to the indirect cause
of frequently field effects on living organisms. Water structure, under the action
of weak varying magnetic fields was investigated by the methods of absorption and
luminescent spectroscopy [7], in which the changes in water structure is due
to the clusters presented in water which control the optical heterogeneity of the

Iwasaka and Ueno [8] discovered that the near IR spectrum (900-2000
nm) and refractive index of water were affected by a strong magnetic field (up
to 14T) and reported that, there is a possibility that the magnetic field affects the
formation of hydrogen bonds of water molecules. Inaba et al. [9] suggested that
the observed magnetic effects on water molecules may somehow be due to that
the magnetic field strengthens water hydrogen bonding, but they commented
that the exact mechanism behind these results remains a mystery.

The aim of the present work is to investigate the effect of static
magnetic field of different strengths up to 5 kG on the biophysical properties of
distilled water.
