摘要：

A new type of rheometer capable of measuring local viscosity as well as elasticity of translucent mediums is described. This apparatus uses a magnetic sphere maintained in levitation by a magnetic field. The measurement of the reaction force exerted on the sphere when a straining field is induced around the sphere allows us to measure the rheological parameters of the medium with an accuracy of 3% for a large range of variation of elasticity and viscosity. Examples are provided for different classes of mediums.
