Just imagine how well the local hardware store staff knows Brainiac75 every time he makes a video.
Can you measure the increase in air pressure near a magnet?
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.
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....
@@erikziak1249i'll have to do some research on that. Maybe some other people have studied it.
@@erikziak1249 We are too late. Someone made a patent patents.google.com/patent/US7771509
But I bet they didn't create the device.
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.
Nitromethane can burn in the absence of ambient oxygen, using a fiberglass wick.
Or maybe, you could try testing each theory one by one, without the use of flames, the air displacing the flame theory, for example can be tested with any sensitive system that would detect the air being displaced by the magnet.
i was thinking the same, my idea is that the charged particles in the flame move mecause of convection and so get deflected as the cros the magnetic flield lines.
@@laharl2k I don't think the ionization plays a significant role. Fire is a quasineutral plasma, the intermediate products have a fairly even distribution of ionization.
Maybe a Bunsen burner with oxygen feed at the bottom, then set up to burn in a nitrogen filled container.
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.
Exactly what I was thinking should be done
I think the results would be the same, even if you light oxygen as a fuel in a propane atmosphere.
Maybe not a steel tube, though?
The magnet's bite is worse than it's bark.
Oo
I've just try with my own 35mm wide neodymium magnet and a lighter. Came closer and closer and... lighter escape of my hand and hit the magnet... Feel dumb xD
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.
Dude it's Ethan Overwatch!
I love videos where the observer becomes the Scientist drawing their own conclusions. Anyone can rig a experiment for any outcome they want.
Make sure that the magnet doesn’t heat up! Great video
Aluminum Oxide why?
@@Poppacap79 I know what he means but the flame has such a low temperature that it won't happen.
If magnets get high enough temperature it will lose its magnetizing power.
Poppa Cap if it heats up too much it weakens the magnetic field
@@Canadian_Teemo Candle flames certainly are hot enough, by a lot. Those bigger magnets will take a while, but for smaller magnets (say, 10mm diameter and below) it only takes a few seconds for them to fall off of whatever they're stuck to due to loss of magnatism.
@@DaffyDaffyDaffy33322 I just did some research and you are correct. I underestimated the heat generated by the candle flame.
No creo que sea necesario decir que se viene por parte de UPDT, solamente hay que disfrutar el video y la explicación del por qué pasa esto :D
Brilliant. Very convincingly explained. Thanks for sharing.
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!
Al quien mas viene de updt
Presente
Probing a flame is something I could see ElectroBOOM doing 😂
Beyond that it's essential to life, the only thing I knew about air is that it's thermal reactive, it expands when hot and contracts when cold. That's why our cars get tire warning lights in summer and winter for overpressure and underpressure respectively. It never occurred to me that air was paramagnetic as well. Learning something new with every video, thank you Sir Brian!
A few moments ago I randomly thought "Can a magnetic field affect a flame?" and here I am. GOBLESS the internet.
Never thought I'd learn something new about two balls put together with fire.
Interesting... it makes me wonder if you could effectively extract oxygen from air using a series of powerful magnets.
I was admittedly excited about the confirmation that diamagnetism is part of the answer, because at the beginning of the video I guessed that before the intro was even over. I'm proud of myself. :P
There is a tiny amount of plasma in fire. It's not much, but it is enough to create an ion wind away from the magnet. If you'll notice, the effect is more pronounced at the base of the flame, where it is more blue and the ions are in higher concentration.
You're having to much fun dude!!! Awesome. Thanks for the video.
Flames reacting to high voltage and static charges would be a cool video idea
Creepy, weird comment. Was just about to go to bed and saw you had a new video up. Your voice is so relaxing, and I love your content
Further tests are necessary with an oxy-propane flame in a vacuum. This would help support the paramagnetic air displacement hypothesis.
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!
This should have WAY more views
It's the material in the wicks some have threads of metal. Metallic ions in the combustion is what is making the flames dance in the presence of a magnetic field.
It is simple experiments like this that make you wonder how a Quasar can consume so much mass and energy. Cheers.
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.
One of the best channels on TH-cam
06:58
Woooah dude, did you really sacrifice a second sponge just to make them match the plastic cap colors? Even though you knew that the sponges get obscured by the magnets?
That's some brutal determination.
Hooray! Science time! Thank you brainiac 75!
Brainiac is back! I really missed these :D
Thank you for coming back, you're one of the few channels that can subside my thirst for science. Looking forward to more.
How have you been? :)
Hehe, I do upload each month, but maybe you are only recommend my videos with 'Monster magnet meets...' in the title? Try clicking the notification bell if you want to tell TH-cam to show every of my video.... Thanks for watching this one, Sacred :D
@@brainiac75 I do have the bell set up in order to show every video, it's just that I am subscribed to channels with a very constant upload schedule and you get used to seeing new videos very often. Of course, quality over quantity is best, I love every video of yours and I won't complain at all for your upload style. I'm sorry for the misunderstanding.
Thank you for your concern and reply.
You've basically invented a Candle dimmer.
Great educational video though :)
That was a very excellent video. I would have never thought that a magnet would have altered the flame. The way you present your evidence is very beautiful. I've been a subscriber for a little while and I've seen your channel change and get better more professional excellent keep up the great work Brian
Thank you very much, Joshua. More to come :D
I once put a notebook computer with an old school CRT monitor on the passenger seat of my van. When driving on the Interstate Highways, the image on the CRT monitor was effected by the MAGNET fields of the rebar encased inside of the concrete road bed. Go figure.
My HS physics teacher had a big block of hematite. We could get small iron pieces to orbit the block before they collided. That would be a cool video
If there were smoke, you could see how the particles of smoke moved and from that understand how the air was moving. If the magnet is really repelling the flame, a styrofoam boat with a candle and a magnet fixed to the boat should propel itself along.
Flames are definitely conductive, just not at the few volts of a DMM probe. At higher voltages they become extremely reactive to electricity and adding more ions to the flame increases this effect. It can be used to make plasma speakers which are more efficient than air-ionized ones.
We need more tests with candles and electro magnets... make the flames dance to the beat :D
1:25 It rhymes so perfectly LOL.
Plot twist: Everything is magnetic,
you've just not used a big enough magnet.
I'd suggest running small/slow pump with intake hose as close as possible to magnet, use captured gas in to flame test and see if it is oxygen in majority.
That sound of the CRT... GRRR
favorite quote: "time to double the power"
This raises the question whether it is possible to concentrate oxygen present in the air simply using magnets.
There is something very satisfying about watching a flame dance without actually touching it , thank you , your videos always teach me something new , this is going to be a fun topic to talk about with my friend , keep up the amazing work that you are doing , I still get nervous when you are working with the giant magnet please be careful
As always sorry for any grammatical errors
PS: greetings from Iran 🌷💓
Thanks Abteen. Glad you always like and comment on my videos :D
Always love watching these videos because I'm always always learning something new
loved it, thanks for taking the time to make and post this video
Spectacular, man. Very nice.
2:55 oh look you can see his face in the ball
Magnets are spacetime whirlpools.
Black holes reaches the ocean floor however.
This was refreshing and enlightening. You put it simply enough that even I could grasp what was going on. Brava/o!
Air is Paramagnetic! Cool!
I wonder how that might be applied industrially.
It would be really interesting to see what effect the magnet would have on some evenly displaced smoke.
Hmm I think it depends on the material the smoke is made of (and it's magnetic properties), maybe if it's more magnetic than air (or is slightly repelled) you could seperate the solid phase from the gas phase of the smoke.
Before: Roasting marshmallows
Now: Roasting magnets...
i greatly appreciate your magnet videos...i have not enough overall $ to do some of those experiments, but are all things i have wanted to do
So it's a mixture of cow and palm oil/fats?
FYI the magnetic field of normal candle flame (why it has a stable shape) is very self contained so it doesnt changes shape easily when exposed to outside sources but if it was a flame tornado it should be more easily manipulated. (this is going on the theory of the flame battery where a bigger flame increases the electrical discharge.
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.
That’s also the same principle that makes flames get repelled by gravity causing them to want to rise on earth! :)
You never disappoint Brian. Always good, educational content!
Ben from AppliedScience did a vid about controlling a flame with magnets.
At 6:31 you could almost have a little piece of cone incense stuck to magnet, so you could see a visual of the air drawing around it. Additionally I would like to see the results on the flame if you had both those magnets set to repel each other. You might also ground the candle wick, they do have a little metal wire in a lot of em, grounding it might result in a different effect.
Now you know one of the flame fears😂👌. Btw great vid 😁👍
By your logic the magnet is essentially pulling in Oxygen which should make the flame grow bigger which is doesn't?
I think from what we see with the one sided magnet is that it's pulling denser air closer, which means the lighter hot air will end up on the exterior. Similar to how Helium will want to go towards less dense air, even though we might think that gravity should pull it down, it's actually the dense air pushing the light away. I think that's what he is explaining at 6:30 where it says "High temperature = Low density" and "Lower temperature = Higher density". And I think what you say does occur when there are two magnets at 8:24 where the flame gets higher than normal.
If you have liquid air you can actually see the air getting attracted to the magnet and you can lift it up with a magnet.
Maybe a colorant or some type of smoke in the air will indicate the air rushing towards the magnet between the magnet and the flame?
Would be nice to have some smoke tracks to visualize the flow of air between the magnet in the flame.
I wasn't going to watch this because the thumbnail looked like a click bait. Didn't know the flame would deflect that much ^^
Congratulations on half a million subs
This affect is caused by the centrifugal part of the magnet this resembles a torus the outward field of the magnet.
The burning creates + and - ions that are affected by electric and magnetic fields. A + charge is repelled.
Maybe try putting a neodymium magnet on an induction desk. Just keep your ears safe from the pitch sound, its intensity could be mutliplied by the magnet's force.
Oooooh, that gold looked nice.
*My mind is slowly melting while I watch in agony*
I like how the multimeter does a quick shout out to satan before getting ready to meter values. :P
So, technically, we can conclude magneto is able to control fire. That makes him a bit more badass than usual, right?
This is one of my fave science channels
Very nice video, as always with astonishing image quality and presentation, everything was very well explained! Once more, Congrats! About the flames, I think we can call it "case closed"!
Nice informative video
The Carbon in the Flame makes it Deflect
Alguien viene de un poco de todo?
Claro que si mortis
put the candle into a crystal vessel opened at the two ends, then you can probe that is in fact the air that surround the candle
Great to see more magnet videos!
Create a box with all magnets on the inside some how super glued, on all sides of the box but from the interior of it then create a magnetic ball that pushes itself against all the magnets you glued to the box so it the magnetic ball hovers in center or so it may move everywhere inside the box hovering freaking out.
Thats the coolest lighter i've ever seen!
There is a type of camera setup that shows air currents. If you set up this Schlieren thing, you might get more answers.
The flame experiments are very interesting but has anyone tried to enrich the oxygen content of an engine by peeling off the oxygen from the air at the inlet manifold prior to the carburettor. I worked on an old Swedish design oxygen analyser many moons ago when magnets weren't so powerful which suggested it could be possible. Likewise it might be possible to enrich air for patients using a similar technique without the need for oxygen bottles.
Excellent video thank you!!
Very nice video. I wonder if there is a way to use a magnetic field to put out a fire. Maybe pulsing the field to prevent combustion. If you could start with putting out a candle and then upscale to a plane over a forest fire would be one of the best inventions this century.
Magnets have the problem, that air is not a good 'magnetic conductor' (it has low permeability), so if your idea is possible, the magnet would have to be very close to the fire. In this case there are cheaper ways than a giant magnet :) Thanks for watching!
The footage from this video implies that you can theoretically blow out a candle with a strong enough magnet?
Its the plasmatic part that is the main reason for it to move.
You should try testing it in either a higher or lower Oxygen concentration, or an oxygen mix with the same partial pressure of oxygen but which has a lower average susceptibility.
Esto es un poco de todo 😎
Your videos are awesome!! Thanks!!!
Never knew this. Nice video!
I wonder if given the attraction of Oxygen, and repulsion of almost all the other elements found in air, if you could use a powerful magnet to create a oxygen rich gas.
Two balloons connected with a bit of pipe, big magnet at one end and leave it to sort itself out maybe?
If air is paramagnetic, wouldn’t that mean there would be continuous airflow around strong magnets?
No, for the same reason a magnet dipped in iron filings don't have a constant stream of metal particles around them. Once all that can be attracted has been, it stays.
@@@galfisk While the wording is off, Myrcella has a point. If oxgen is magnetic would that mean a magnet can be used to separate O2 from N2. As it was shown that it is quite a strong effect.
Dragos Coco so in a low oxygen environment just duct tape a giant magnet to your face?
@@jbh759 I don't see how that could possibly fail.
+Joe Hoyt That would be the implication of that supposition. Separating oxigen would reach a new cheap.
Please I would live to see you do a "Singing Flame"! I love your videos!
That's good science baby!
You need to continue.
That was amazing... has to be the best science video I have seen in a while!!!!!
I agree
