Can you measure the increase in air pressure near a magnet?
@erikziak1249 5 жыл бұрын
I would expect the air pressure to decerase near the flame. Basically a sort of Venturi effect. I might be very wrong with my assumtion, as it would form in an unclosed area, not a pipe.

@@erikziak1249 I think the Bernoulli Effect would apply in that case. Anyway, I meant measuring the effect of the magnet on the air without the flame. Also measuring the O2 concentration might be interesting, but I think we need precise measurement devices for these things.
@erikziak1249 5 жыл бұрын
You are correct and you propose a very interesting idea. Now the question is, how to measure it scientifically? Could it be used to enrich the air with O2, e. g. in high altitudes? How would such an apparatus look like? How efficient would it be? What could we expect? Questions over questions....

One possibly interesting experiment is to use a reverse flame. I recall Cody's Lab doing a video on an oxygen flame in a propane environment. You could make an atmosphere of some hydrocarbon that does not respond to a magnet, and flow a stream of oxygen through a small steel tube then light it. Then see if the magnet will deflect the oxygen flame towards it due to paramagnetism.

It'd be really hard to falsify the results considering a flame needs oxygen to even exist. We would need to find a flame that can enter a plasma state in the absence of oxygen in an a inert atmosphere to test. The flame is also susceptible to electrostatic fields, so we cannot be completely neutral.

This is such a brilliant, elegant explanation. I'm embarrassed I didn't arrive at it myself after having seen the effect shown so clearly in other places like Ben Krasnow's channel. You've effectively rediscovered a version of the magneto-Archimedes effect published some years back (see one of my earliest videos). Everyone was so distracted by the ionization potential of the flame, including myself, that it blinded us from the obvious and more parsimonious explanation. I now believe the relevant paper here is probably Ueno and Harada's 1987 "Effects of magnetic fields on flames and gas flow". Most excellent work.

I think the flame got bigger/smaller when you moved the newly created contraption was because the air was repelled into the flame making it burn bigger and faster, and opposite for when the flame was smaller. Thus the flame itself wasn't directly effected from the magnetic fields but rather from the air being pushed and pulled by the magnet and this resulted in this effect. Just a thought though, I'm no scientist.

Really nice! Maybe, you could try hanging very small sheets of paper(or a any material that has very weak diamagnetism/paramagnetism, being almost neutral to the magnet's force) with as little mass as possible, and putting your strongest magnet near it, to see if it would be pushed away from the magnet due to the air being attracted to it. For even further research, you could use a vacuum chamber, take out all the air from it, add any diamagnetic gas(like argon) and doing the same test inside the chamber, and if the magnet indeed pushes the flame due to the air displacing it, the first test would be true and the second false. I love your videos! Keep with the good work!

Interesting effect! However you lack a control test: in a environment without oxygen there should not be any deflection. Creating a flame in an oxygen starved environment is hard, but can be done if you seperate the oxygen inlet. However, I immediately thought of magneto hydrodynamics (MHD) . The flame consists of moving magnetic molecules, thereby they experience a Lorentz force. The equations for this also describe the effects in the core of the earth. Pretty cool stuff!

Years ago I used a fish tank air pump to draw oxygen from a magnet. I directed the flow into a Bunsen burner and used a thermocouple to measure the increase in temperature to confirm the increase of oxygen. The setup was crude so I could not determine any absolute values. That was long before the availibility of rare earth magnets and the thermocouple was a simple twisted wire. The effect was very slight but it did work. It was an interesting experiment.
@christmassnow3465 4 жыл бұрын
To test if the oxygen is attracted, and not the flame is repelled, you can do the following test: ignite a mix of air & fuel. Let the flame exit through a hole into a vacuum chamber. You can then repeat the magnet test in the vacuum chamber. Another interesting test: put a candle on the surface of a monster-magnet, where the oxygen content is said to be higher. Light the candle and watch the air flow above it, as fresh oxygen is constantly pulled to the magnet, replacing the exhaust fume.

8:40 When you are playing with the double magnet and the flame there is a very noticeable lag between magnet position and flame orientation. The flame effectively seems to be reacting to where the magnets were, 1/4 of a second before. This strongly supports the thought that the flame is not being directly pulled/repelled by the magnet, but rather by a secondary effect. I.E. the "wind" caused by the magnets' effect on the air surrounding them and the flame. Maybe some tests with smoketrails in the air, if you can find a smoke substance that is very neutral magnetically and thus not itself affected, just carried by the air movements?

I think your 3rd theory is the major player. The conductive plasma is flowing upward, cutting the lines of flux from the magnet. The induced eddy current in the flame reflects the magnetic field, creating repulsion. If you took the big, flat magnet, and held it edge wise to the flame, it would have had a big effect on the flame, just like passing aluminum through the field. That explains why the flame is repelled when you have a north pole on one side, a south pole on the other. Just drop a bar of aluminum through the gap, you'll see the force i'm talking about. It has to be moving to do it, and the rapidly rising flame provides that velocity. Granted, the plasma has high resistance, but those Neodymium Iron Boron magnets do generate a pretty dense magnetic field, and it doesn't take much force to influence a low density flame. the up draft velocity of a flame is actually pretty quick, due to the buoyancy of the light flame.
