First Experiment : If you pass a current through salt water in the presence of a magnetic field we obtain a vortex, it is the same principle as the homopolar motor. Second Experiment : If you have a ZVS driver that generates a 20k volt plasma flow you can generate a plasma vortex if in the presence of a magnetic field. This is the magnets i used in the first 2 videos. Ferrite Magnets FE-R-40-22-09 http://sumag.net/fe-r-40-22-09-x01 FE-R-100-60-20 https://sumag.net/fe-r-100-60-20-x01 Third experi

How to make a vortex ring

Create half-ring vortices in a pool by sliding a plate through water and adding food coloring to the ends.

The Vortex Ring State (VRS) is a dangerous condition for helicopters, occurring when the rotor descends into its own downwash, creating a turbulent vortex that causes a sudden loss of lift and control. This usually happens during vertical descents or hovering, especially at high descent rates and low airspeeds. Attempts to increase power can worsen the vortex, accelerating descent unexpectedly. To recover, pilots use forward cyclic control to move the rotor out of its downwash and reduce collect
