Weak transverse magnetic field effect on the viscosity of Ni(NO3)2H2O solution

Experiments performed at 25°C show that transversally applied magnetic field H of strength of 12 kG; at high concentrations decreases the viscosity of Ni(NO₃)₂H₂O solution. At low concentrations, however, the applied magnetic field increases the viscosity of Ni(NO₃)₂H₂O solution in such a way as the observed effect value approaches the already measured viscosity increase of the pure water at the same magnetic field and temperature conditions.
