What is it about?
One central characteristic of fluids is the viscosity. For example, honey is more viscous than oil. Several industries need to know the viscosity of fluids, including the oil/petroleum, the paints, the cosmetics industry, even the pharma. We here develop a method to precisely measure the viscosity of fluids with a user-friendly and inexpensive device.

Why is it important?
Scientifically, this work connects magnetic measurements with fluid dynamics, which two fields are so far rather disjoint. Such connection could inspire further technological developments. On the commercial applicability, this work introduces a viscometry device aiming to fill a gap in the market in the price range between about $500 and $3000, while providing competitive performance needed by several industries.
Perspectives
The work for this article was performed by two senior undergraduate students with very simple equipment. It is always a joy to see that such kind of work can lead to what I hope will be an inspiring research article, along with the possibility for commercial application.
