Increase of water viscosity under the influence of magnetic field

Effect of applied magnetic field on the water viscosity between 298 and 323 K has been investigated. A higher absolute viscosity has been observed in the presence of applied magnetic field compared to no field which has been explained on the basis of stronger hydrogen bonds. The measurement is found to increase consistently at higher temperatures. The relative increase in viscosity Delta eta/eta(0) is of the order of 10(-3) in a 7.5 kG transverse magnetic field where Delta eta is the viscosity change compared to the no-field viscosity eta(0) at a given temperature.
