**Magnus Effect**
**Definition**
The Magnus effect is a physical phenomenon where a spinning object moving through a fluid (such as air or water) experiences a force perpendicular to the direction of its motion and the axis of its spin. This effect causes the object to curve away from a straight trajectory.

## Magnus Effect
The Magnus effect occurs when a rotating body, such as a ball or cylinder, moves through a fluid medium. The rotation creates a difference in fluid velocity on opposite sides of the object, resulting in a pressure differential according to Bernoulli’s principle. This pressure difference generates a lift force perpendicular to the object’s velocity and spin axis, causing the object to deviate from a linear path.
### Historical Background
The effect is named after Heinrich Gustav Magnus, a German physicist who described the phenomenon in 1852. It has since been studied extensively in fluid dynamics and applied physics.
### Applications
The Magnus effect is commonly observed in sports, influencing the trajectory of balls in games like soccer, baseball, tennis, and golf. It is also relevant in engineering, such as in the design of spinning projectiles and rotor ships that use rotating cylinders to generate thrust.
### Physical Explanation
When an object spins, it drags fluid around its surface. On one side, the spin direction aligns with the fluid flow, increasing velocity and reducing pressure. On the opposite side, the spin opposes the flow, decreasing velocity and increasing pressure. This pressure difference produces a sideways force, altering the object’s path.
