The force exerted on a rapidly spinning cylinder or sphere moving through air or another fluid in a direction at an angle to the axis of spin. This force is responsible for the swerving of balls when hit or thrown with spin.
- ‘A lift-producing arrangement suitable for driving a boat by the Magnus effect comprises an elongate tubular envelope mounted for rotation about its longitudinal axis.’
- ‘The lift force is the upwards or sidewards force that is responsible for the Magnus effect.’
1920s: named after Heinrich G. Magnus (1802–70), German scientist.
