The effect of a static magnetic field on the hydrogen bonding in water using frictional experiments

•There is smaller friction coefficient in magnetized water than in water.•The stronger magnetic intensity, the lower the friction coefficient in magnetized water becomes.•Magnetic field weaken hydrogen bonding in water. The effect of a static magnetic field on hydrogen bonding of liquid water has been examined by frictional experiments in this paper. It was found that the friction coefficient was smaller in different intensity magnetized water than in water, and became larger with the increasing water temperature. According to the thermal motion of water molecule known to become stronger and thus hydrogen-bonding gets weaker when water temperature increases, a thermal dynamic effect analogous to the increase of temperature was assumed, and the frictional differences were probably because of the weak effect of the magnetic field on hydrogen bonding among water molecules.
