Magnus Effect
The Magnus effect is a physical phenomenon describing the lateral force generated when a rotating object moves through a fluid. Derived from Bernoulli's principle, rotation causes asymmetric flow velocities on opposite sides of the object, producing a pressure differential that results in a deflecting force. It is the core physical principle used to explain the curved trajectories of spinning balls.

The Magnus effect influences the flight path of a spinning ball by altering its aerodynamic trajectory, and the degree of trajectory curvature itself carries spin information.
According to the Bernoulli principle, the air pressure is lower on the side of a spinning sphere where airflow velocity is higher, generating a lateral force perpendicular to the direction of flight that pushes the ball's trajectory toward the low-pressure side.
The principle of rotor sails is based on the Magnus effect—a rotating cylinder in an airflow generates thrust perpendicular to the wind direction.
The Magnus effect was described by German physicist Heinrich Magnus in 1852.
