1. Imagine a big river with water flowing constant velocity , assume there is a whirlpool at center as shown in the figure.
2. Because of the magnus force the whirlpool should move towards left or right towards river bank depending on the spin, but it does't happens it just stays fine in its position....so why?
3. I belive that magnus force will exists in whirl pool only when the velocity of water changes (acceleration), not just velocity , since the whirlpool is itself a part of the water flow.
4. apply the same to tornado and faraday's law of electromagnetic induction (as anology).
