Magnus effect
Description
The Magnus effect is the commonly observed effect in which a spinning ball (or cylinder) curves away from its principal flight path.The overall behaviour is similar to that around an airfoil with a circulation which is generated by the mechanical rotation, rather than by airfoil action. On a cylinder, the force due to rotation ( known as Kutta-Joukowski lift), can be analysed in terms of the vortex produced by rotation. .
