Magnus effect
The Magnus effect is the phenomenon whereby a spinning object flying in a fluid creates a whirlpool of fluid around itself, and experiences a force perpendicular to the line of motion and away from the direction of spin. The overall behaviour is similar to that around an aerofoil (see lift force) with a circulation which is generated by the mechanical rotation, rather than by aerofoil action.[1] In many ball sports, the Magnus effect is responsible for the curved motion of a spinning ball. The effect also affects spinning missiles, and is used in some flying machines.
German physicist Heinrich Magnus first described the effect in 1853, but according to James Gleick, [2] Isaac Newton described it and correctly theorised the cause 180 years earlier, after observing tennis players in his Cambridge college.

This is known as the Magnus effect. This reduced friction together with its high relative mass and angular momentum, allows Halospheres to accelerate to extreme velocities. The halo effects are a result of its spherical shape. Halospheres Forged from steel and plated in real gold, Halospheres is a realÃâà...

Rotor Sails are deck-mounted rotating cylinders that utilise the Magnus effect to create a propulsive thrust. The Magnus effect is a force that acts on a spinning body in a moving airstream. Because the Magnus effect acts perpendicularly to the direction of the airstream, the optimum wind direction for FlettnerÃâà...

In the early 20th century, scientists proposed using the Magnus effect to propel ships. German engineer Anton Flettner replaced 420 square meters of sail cloth on the schooner Buckau with two 15-meter-tall steel rotor sails, which were set spinning using a small engine. Flettner showed that wind travelingÃâà...

[PeterSripol] has made an RC model airplane but instead of using normal wings he decided to try getting it to fly using some KFC chicken buckets instead. Two KFC buckets in the place of wings were attached to a motor which spins the buckets up to speed. With a little help from the Magnus effect thisÃâà...

The reason this works is because of something called the Magnus effect. In essence, if an airborne object like a sphere or a cylinder gets enough spin, it will curve from a straight flight path based on the way air travels around the spinning object. This is the same force that lead to that viral gliding basketballÃâà...

Have you ever wondered how football players are able to bend the ball like they do? Perhaps you've noticed how other spinning solid objects seem to magically move sideways as they fall? Why is this? It all comes down to the wonder of the Magnus Effect. In this article, we'll have a quick look at what it isÃâà...

So, just cause it's the sweet space between Christmas and New Year's doesn't mean you can't still learn new, cool things — like physics. Today's coolness is the Magnus effect, which is all about how spinning, flying things get driven sideways. You've seen this in the way spin on a tennis ball can make it doÃâà...

Next, by blowing into the steel nozzle that's included, an additional force is then created to accelerate the spheres. Once the angle is just right, users can see the spheres themselves reach unbelievably high speeds. In order to achieve its extreme velocity, Halospheres utilizes the Magnus effect to generateÃâà...
