    Named after his discoverer, Heinrich Magnus, the Magnus effect is a phenomenon in fluid mechanics that is a force exerted on an object (such as a cylinder) rotating in a fluid. Airships made using the Magnus Effect can increase the lift of the airship. The formula is as follows:

    f=s(w x v), f is the force, and w is the angular velocity.

    v is the linear velocity, which is a vector, with magnitude and direction. x is the cross product.

    The Magnus effect is a phenomenon in fluid mechanics in which when the rotational angular velocity vector of a rotating object does not coincide with the object's flight velocity vector, a transverse force is generated in the direction perpendicular to the plane composed of the rotational angular velocity vector and the translational velocity vector. Bernoulli's principle is essentially the conservation of mechanical energy of a fluid. Namely:

    Kinetic energy, gravitational potential energy, pressure potential energy, constant. The most famous corollary is that when the flow is at a constant height, the flow velocity is high, and the pressure is small.

    It is important to note that since Bernoulli's equation is derived from the conservation of mechanical energy, it is only suitable for ideal fluids with negligible viscosity and non-compressibility. Suitable for ideal fluids (no frictional resistance). The terms in the equation represent the difference between the kinetic energy, potential energy, and static pressure energy of the unit fluid.

    The Magnus effect, named after his discoverer, Magnus, is a phenomenon in fluid mechanics that is a force exerted on an object (such as a cylinder) rotating in a fluid. The Magnus effect can be used to explain phenomena such as curveballs in table tennis, banana balls in football, and so on. In 1742, Benjamin Robbins, a British gun engineer, explained the deviation of the trajectory of a rifle projectile in the Magnus effect.

    The Magnus effect is as follows:

    The Magnus Effect, named after its discoverer, Gustav Magnus, is a phenomenon in fluid mechanics that is a force exerted on an object (such as a cylinder) rotating in a fluid.

    The Magnus effect is very common in ball games, not only in football and table tennis, but also in tennis, baseball, volleyball, basketball, etc., so the study of the causes of the Magnus effect and its application in ball games has important guiding significance and practical significance for the teaching level, training effect and competition performance of ball games.

    In addition, the Magnus effect is a nonlinear complex mechanical phenomenon, and in-depth study of its mechanism and laws will play a guiding significance for the design of rotating projectiles and missiles, aerodynamic performance analysis and guidance control.

    This effect was discovered by the German scientist Magnus in 1852, hence the name. A circular column rotating at a moderate speed in a stationary viscous fluid will drive the surrounding fluid to move in a circular motion, and the velocity of the fluid decreases with the increase of the distance to the cylinder.

    Such a flow can be simulated with a point vortex of strength at the center of the circle. The Magnus effect can then be explained by the annular flow of an inviscient, incompressible fluid around a cylinder (see Cycloless Motion with Annular Quantities).

    The Magnas effect was used to propel ships to the power of the wind, replacing sails with several rapidly rotating lead-straight cylinders. The experiment was successful, but it was not adopted because it was not economical. The trajectory of sidespin and curve balls in football, volleyball, tennis, table tennis, etc., is also due to the Magnus effect.

    1.Increase the spin velocity of the object. A faster spin will produce a greater moment.

    2.Increase the density and surface area of the object. Objects with high density and large surface area are more prone to the Magnus effect.

    3.Change the direction of rotation. In some cases, changing the direction of rotation may enhance the Magnus effect.

    4.Adjust the properties of the medium. When moving in liquids or gases, adjusting parameters such as temperature, source pressure, and viscosity in the medium may affect the Magnus effect.

    5.External factors such as electric field drifting or magnetic fields are used to regulate the Magnus effect. These external factors can affect the hydrodynamic properties around the object, which can affect the magnitude and direction of the Magnus effect.

    The Magnus effect is a phenomenon in fluid mechanics in which a transverse force is generated perpendicular to the plane of rotation and translational velocity vector when the grinding angular velocity vector of a rotating object does not coincide with the vector of the object's flight velocity. Bernoulli's principle is essentially the conservation of mechanical energy of a fluid. Namely:

    Kinetic energy spine gravitational potential energy Pressure potential energy constant. The most famous corollary is that when the flow is at a constant height, the flow velocity is high, and the pressure is small.

    is a phenomenon in fluid mechanics, which is the force exerted on an object (such as a cylinder) rotating in a fluid.

    Principle: If an object translates and rotates at the same time, then its flight trajectory will be offset, and the fluid on one side of the direction of the shift will rotate with the object, and the rotation will be faster, resulting in negative pressure, while the other side will generate positive pressure, and the pressure difference between the two sides will produce a lateral force.

    The Mags effect refers to the fact that in fluid mechanics, if a cylinder rotating about an axis moves laterally, it will be subjected to a force perpendicular to the direction of motion given by the fluid. This phenomenon is known as the Magnus effect.

    For example, in the banana ball in football, the faster the ball spins, the greater the arc.

    The phenomenon in which a cylinder rotating on its axis is subjected to a force perpendicular to the direction of motion by the fluid when it moves laterally is called the Magnus effect.

    In fluid mechanics, if an object translates and rotates at the same time, its trajectory will be shifted, and the side of the deviation will rotate faster, resulting in negative pressure, while the other side will generate pressure, and the pressure difference between the two sides will produce a lateral force.

    It is the combination of the rotation and the rotation of the sphere and the flattening, when the ball moves in the air, the rotation and the friction of the air will lead to the difference in the density of the two air in the ball, and a deflection force will be produced, and the ball will break away from the original straight track! The faster the rotation, the greater the distance from the straight line.

    The Magnus Effect:

    The easiest way to generate the amount of torus around a cylinder is to rotate the cylinder. Since real fluids are viscous, the rotating cylinder must drive the fluid around the cylinder to move, resulting in a ring around the cylinder.

    Therefore, when a cylinder rotating about its axis moves laterally, it will be subjected to the force perpendicular to the direction of motion given by the fluid. This phenomenon is called the Magnus effect.

    In ball games, the Magnus effect can be used to cause the ball to drift laterally. If the resultant force of the shot does not pass through the center of the ball, the ball will have a rotational motion as well as forward motion. Due to the Magnus effect, the ball moves forward and produces a lateral drift.

    The figure shows the drift phenomenon of the motion of the sphere.

    Calculation formula: f=pi*air density*v*r 3*w

    The Magnus effect, named after its discoverer, Heinrich Magnus, is a phenomenon in fluid mechanics that is a force exerted on an object (such as a cylinder) rotating in a fluid.

    When the rotation angular velocity vector of a rotating object does not coincide with the object's flight velocity vector, a transverse force will be generated in the direction perpendicular to the plane composed of the rotation angular velocity vector and the moving velocity vector. The phenomenon of deflection of the flight trajectory of an object under the action of this transverse force is called the Magnus effect. The reason why a rotating object can produce force in the transverse direction is that the rotation of the object can drive the surrounding fluid to rotate, so that the fluid velocity on one side of the object increases and the fluid velocity on the other side decreases.
