Question
What is Magnus effect? Explain.
Solution
When a spinning ball is thrown in the blowing air the path of the ball becomes curved. This is known as Magnus effect.
This effect arises because layer above the ball moves in the direction of spinning ball. So, the velocity of layer above the ball increases and similarly the velocity of the layer below the ball decreases.
Hence, due to Bernoulli's theorem the pressure above the ball will be less than below and hence due to this pressure difference the ball follows a curved path.
