Abstract A new method to measure the magnetization dependence of the viscosity in polarized liquid3He is presented. The magnetization is obtained by “brute force polarization” at 50 mK in magnetic fields up to 11 T; it is subsequently destroyed by saturation of the NMR signal. Irreversible heating due to the saturation and relaxation of the magnetization is easily observed using the viscometer. Comparison of the calculated temperature evolution with the behavior of the viscometer shows that the viscosity is slightly magnetization dependent. Our result, a relative increase of the viscosity of 0.3±0.15% for a polarization of 3.9% and a pressure of 30 bar, disagrees with a prediction based on the “nearly metamagnetic model” and the first measurement based on the rapid melting of polarized solid.
