The Magnus effect is the primary scientific principle behind why spinning balls curve, dip, or lift in the air. Named after German physicist Heinrich Gustav Magnus, it describes how a rotating object alters the fluid dynamics of the air surrounding it. The Aerodynamics in Flight
When a ball travels through the air, it experiences oncoming airflow. Introducing a spin causes the surface of the ball to manipulate that airflow through friction:
