Research Abstract

We(research group) developed a new apparatus of viscosity measurement based on the principle of electro-magnetically driving of the metal probe in a non-contact manner. The system has an advantage that is completely free from the contamination to both of the sample and the measurement apparatus. The system is composed of the dipole electromagnet and the precise measurement of the rotation angle of the sphere with the optical lever technique.
