Editing Magnus effect (section)

=== Inverse Magnus effect ===
In [[wind tunnel]] studies, (rough surfaced) baseballs show the Magnus effect, but smooth spheres do not.<ref name="Lyman" /> Further study has shown that certain combinations of conditions result in turbulence in the fluid on one side of the rotating body but laminar flow on the other side.<ref>{{cite journal |last1=Kim |first1=Jooha |last2=Choi |first2=Haecheon |last3=Park |first3=Hyungmin |last4=Yoo |first4=Jung Yul |title=Inverse Magnus effect on a rotating sphere: when and why |journal=Journal of Fluid Mechanics |date=10 September 2014 |volume=754 |doi=10.1017/jfm.2014.428 |bibcode=2014JFM...754R...2K }}</ref> In these cases are called the ''inverse Magnus effect:'' the deflection is opposite to that of the typical Magnus effect.<ref name="Cross">{{cite web |last=Cross |first=Rod |url=http://www.physics.usyd.edu.au/~cross/TRAJECTORIES/Fluidflow%20Photos.pdf |title=Wind Tunnel Photographs |publisher=Physics Department, University of Sydney |page=4 |access-date=10 February 2013}}</ref>
