    "abstract": "We investigate the flow generated by a magnetic stirrer in cylindrical\ncontainers by optical observations, PIV measurements and particle and dye\ntracking methods. The tangential flow is that of an ideal vortex outside of a\ncore, but inside downwelling occur with a strong jet in the very middle. In the\ncore region dye patterns remain visible over minutes indicating a pure stirring\nand mixing property in this region. The results of quantitative measurements\ncan be described by simple formulas in the investigated region of the stirring\nbar\u0027s rotation frequency. The tangential flow turns out to be dynamically\nsimilar to that of big atmospheric vortices like dust devils and tornadoes.",
