Is water a fluid conforming to the Newtonian laws?

From infrared spectra of absorption of pure and magnetized water we discover exceptionally that its infrared absorptions have an irreversible effect during the processes of increasing and decreasing temperature. Then we infer that water is not a fluid conforming to Newtonian laws. Hence we collected the rheology features of pure and magnetized water, and discover that their viscosities decreases with increasing shear stress, speed of shear distortion, intensity of magnetic-field and magnetized time, the speed of shear distortion versus shear stress are some straight lines without passaging the origin of coordinate, their obliquity rates increase with increasing magnetized time and intensity of magnetic-field. Hence we affirm that water, in especial, magnetized water is not a Newtonian fluid, but a plastic fluid. Also, we discovered that there are plenty of hydrogen-bonded chains or clusters of molecules in water, which result directly in its plastic flowing. This alters our traditional understanding to water.
