Liquid Mercury vortex in a magnetic field

In this experiment we see that half of a copper globe is anodized with nickel metallic paint and connected to an electric wire in a direct current pole. In the center of the container there is a brass bolt electrically isolated from the container and connected to another pole of the direct current. At the base of the wooden support there is a large magnet which generates a magnetic attraction. Liquid mercury weighing just over 1 kg is poured into the container. When current flows through the two conductors, it generates a strong magnetic field that supports the system. This favorable condition causes mercury to rotate since it is a very conductive metal.
For the success of the experiment it is necessary to have liquid mercury not less than 1 kg.
The experiment does not work with gallium, as it is a less fluid metal.
The voltage source is given by a 2 volts 45 amps transformer driven by a direct current inverter.
The current absorbed for operation is approximately 38 amps.
The speed of rotation of the mercury varies according to the weight and the voltage supplied.
* System doesn't work in alternating current.

I like how he dramatically connects the power.

Thank you. No talking and no music. Love it.

This reminds me of the inner workings of a triangular craft called the TR3B. The engine is supposed to have an inner chamber with spinning mercury that creates an electromagnetic field. Mercury has always fascinated me.

Does this process actually change the taste of the mercury?

[psycores]

This is what the ancients used to make flying ships ... at the core of the ship they had a sphere of mercury in a rotation.

[khalliwallivlogs]

This gives me chills, connecting this experiment to Vimana's the flying saucers specified in ancient mythology powered by Mercury, having anti gravitational properties.

Reminds me of Michael Faraday's first motor which also used mercury in a bowl
the setup was a bit different but was basically the same, good demo.

Here's an experiment I wish someone would try:

Make a doughnut shaped copper coil with another doughnut shaped tube in the center of the coil filled with liquid mercury. Connect a wire from the coil to the tube so it makes contact with the mercury. Then use a machine to try different frequencies to see if you can pull power out of thin air from the "Taurus field." Also you might have to have 2 sets of mercury filled tubes so they can run in opposite directions which may be needed.

A: Where did you get that much mercury, and B: what is you amperage? Magnetohydrodynamics is so cool!

[ramseybarghouti]

1. Slow motion please.
2. It would be interesting to study the transitions between laminar and turbulent flow in mercury under various conditions.

[artyom_zdanek]

this is pretty neat, and also i like the fact that a slight amalgam is forming in the mercury as it spins, perhaps from the metal dish itself or the apparatus at the center.

[lillys]

I don't know what I expected to happen.
But I got exactly what the title said.

That sure is a Mercury vortex in a magnetic field.

[valdisbojarevics]

Very nice demonstration! We did a very similar experiment in 1983 published (J. Fluid Mech. (1983), vol. 126, pp. 413-430). The flow starts rotating at a critical current magnitude (about 100 Amperes) due to the terrestrial magnetic field, no magnets are needed. The arrangement was highly symmetrical relative to the central axis. The effect is very similar to the bath tube vortex.

[kreynolds]

"The speed of rotation depends on the voltage." Pretty close but not quite right. A better answer might the amps flow causes a force on the mercury that causes the mercury to accelerate in the magnetic field. As the mercury is centrifugally pushed to the outside, the magnetic fields weaken causing less thrust. The final average velocity is a balance of the lenze forces on different parts of the mercury and the energy dissipated in the mercury because of viscosity, turbulence and ohmic heating. The amps flow depend in part on the voltage and ohmic resistance, but also the surface area in contact with the mercury, as well as the geometry of the contact area and the cross section of mercury that the current travels through, in addition to the temperature of the mercury.

[gavincurtis]

Awesome! Now add more power. But first put the mercury in a hollow toroid shaped former so it stays contained and in contact with the electrodes at all times. At some point, things should get real interesting if your containment vessel (toroid) is strong enough. Chill the apparatus to about -39 C while maintaining vacuum in the containment vessel to reach the superfluid triple point of mercury and try again. Subscribed to see how far you take this. EDITED: removed my impossible to exist -14.7 PSI error.

Mercury :- Damn that's why I spin faster around the Sun

[JoachimVampire]

i imagine it's to avoid dangerous splashes but i wish he would have reversed the polarity almost instantly to see how it would react. slow and steady or chaotic and fast? we will never know
