Viscosity is an important mechanical property of liquid materials referred to in various industrial processes, such as transportation, mixing and coating. Measurement techniques are thus essential for various environments, however, less progress in mythology has been made in recent years, though the conventional method hardly satisfies the variety of users demands: Requirement arises, for example, to the rapid observation, small quantity of samples, and completely closed system for the viscosity measurement. We introduce in this paper the Electro-Magnetically Spinning (EMS) method, which can settle these problems of the conventional methods. This method has unique features such as, non-contact and rapid measurement, small sample volume, disposable usage, measurement under hermetically sealed condition, which are demonstrated in actual rheology measurement of various materials.
