I'm currently doing a project for my A-Level Physics group, and I have chosen to look into the Magnus Effect, however, I'm struggling to find an equation for it? Really need help here! Thank you!
rcgldr said:I'm not aware of real world formulas. There are idealized formulas for spinning cylinders, but these are fairly off from actual real world examples.
Wiki article, the lift force related to Magnus effect is due to diversion of air flow in the wake that trails the spinning ball:

Another archived separation of flow explanation:

The Magnus Effect is a phenomenon in fluid dynamics where a spinning object experiences a force perpendicular to its motion, resulting in a curved path.
The Magnus Effect occurs due to differences in air pressure on opposite sides of a spinning object. This pressure difference creates a force that causes the object to move in a curved path.
The formula for calculating the Magnus Effect is F = ρvωA, where F is the force, ρ is the density of the fluid, v is the velocity of the object, ω is the angular velocity, and A is the cross-sectional area of the object.
The Magnus Effect is used in various sports, such as baseball, tennis, and golf, to control the trajectory and movement of the ball. In these sports, players use spin on the ball to create a pressure difference and cause the ball to curve or swerve in a desired direction.
The Magnus Effect has many real-world applications, including in the design of airplane wings, wind turbines, and sailboats. It is also used in industries such as oil drilling, where it is used to stabilize drilling platforms and guide drilling equipment.
