Noun
Magnus effect (plural Magnus effects)
The phenomenon whereby the path of a spinning object moving through a fluid is deflected in a manner that is not observed when the object is not spinning, explained by the difference in pressure of the fluid on opposite sides of the object.
Like the backspin stroke, however, the axis of spin remains roughly perpendicular to the trajectory of the ball thus allowing for the Magnus effect to dictate the subsequent curvature. Source: Internet
In this circumstance, the Magnus effect will still dictate the curvature of the ball to some degree. Source: Internet
This means that the Magnus effect will have little to no effect on the trajectory of a cork-spun ball. Source: Internet
