Physics made simple, by Dr. Horace R. Drew
The physics of magneto-hydrodynamics, as shown in this teaching video, may provide a plausible explanation for how the mysterious “dragonfly drone UFOs” fly. They usually show a large ring of flat magnets, inside of which we can see a slightly-smaller ring of curved metal electrodes, and above which we can see a long, curved “tunnel” of thick metallic rods, through which an ionic fluid might be pumped downward, so as to provide “lift”.
What other explanation might there be for such strange design-features?
We should be able to build such “floating” UFOs using current physics, as known today on Earth.
We would like to call this kind of propulsion “magneto-aerodynamics”.
A “sideways” Lorentz force, which is needed for magneto-hydrodynamics, may be produced using either DC or AC voltage/current. Most simply, a DC voltage/current may be applied across a narrow channel of conductive liquid, just above the pole of a strong N/S or S/N magnet, by using a permanent neodymium N52 magnet.
This type of set-up is used to pump liquid metals in nuclear reactors. In water solutions, however, the electrolytic reaction which enables an ion-current to flow, between plus and minus DC electrodes, also produces bubbles of gas, which may impede overall fluid flow if they move in an opposite direction to the flow of the water, and which may cause degradation of the two electrodes.
Using an AC voltage/current with an AC electromagnet (wired in series, or in parallel with a resistor) can sometimes be better. Since those two, fast-switching, electric and magnetic fields will remain synchronous in time (say when using 50 Hertz AC from a standard power supply), then an instantaneous, “sideways” Lorentz force should point in the same direction (for flow) throughout any alternating-current cycle.
We used a 120-volt, AC isolation-transformer for electrical safety during these experiments, as well as a simple, AC voltage-regulator which could be adjusted to a “low and safe” 30 volts. Do not try the AC version of this experiment using a standard wall-power-supply or Variac at high voltage!

WARNING: Don't touch the metal when you are testing wireless electricity circuits at 5 amps!
Its relevance to certain kinds of UFO technology has not escaped our attention.
