Abstract
A process and a device for determining the viscosity of a fluid are proposed. Very simple and accurate determination is enabled in that the magnetic particles in the fluid are set into vibration by a magnetic field which varies over time. A measurement of the amplitude and/or phase of particle vibration is used to determine the viscosity or an associated quantity, such as the coagulation of blood or the glucose content.
