| Abstract | Three variants of the rotational viscometer employing a dc motor are considered. The viscometers are highly suitable for liquids of high viscosity, such as glycerol or oils (that is, for [eta] in the range 10-1000 mPa s). The set-ups are very simple and can serve as a first step to designing devices that are more complicated. Experimentation with the electrical motors used in the viscometers provides a deeper understanding of some of the fundamental laws of electricity and magnetism (Lorentz's force, Faraday's law of electromagnetic induction, and Lenz's law). (Contains 6 figures.) (As Provided). |
