Abstract: Effect of a magnetic field on potential energy of liquid water are investigated for first time using classical Monte-Carlo computer simulation and a water model L-J. The relationships between energy and magnetic flux density and temperature have been studied by calculating potential energy and radial distribution function (RDF) of a system containing 64 water molecules. Comparisons with the field-off system are made throughout. It is found that the computer simulation is in agreement with experimental results.
