Magnetic Fields "Bending" Light Paths
HTML-код
- Опубликовано: 21 июл 2024
- I show you how a magnet and ferrofluid can be used to change the orientation of iron particles. The iron nanoparticles can reflect LED lights. This "bending of light" is most likely specular reflection, however there has been no definitive proof. Though this device does not necessarily show magnetic fields, it can show you the effect of the magnetic field on the position of the iron particles.

The device shown here has been called a ferrocell. To be clear, it probably does not show the magnetic field lines. Most likely it shows the specular reflection that results from the iron particles aligning to the magnetic field lines (ruclips.net/video/pc9ghVd1rsw/видео.html). This seems like an active area of interest and there may be some value to the ferrocell even if it doesn't necessarily show the magnetic field lines.

was about to post a link to that ab science vid myself. fair play
Is this guy even human? Is he a higher being from elsewhere??? Or does he literally just sit in a huge warehouse of everything and mix match items all day to see what happens???
At 0:32. He calls those pennies. What pennies are silver because where I come from. Brand new they are a shiny copper, then in a month they turn into an ugly brown...
I FIGURED IT OUT!!! This guy is that child alien from Mac and Me, all grown up!!!
It isn’t an action lab video without a “woah, that is *so* cool”
Haha he sounds so childish doesn't he!
@@analogdistortion the curiosity of a child, which is great for science.
@@DANGJOS I know yeah haha. Just quirky isn't it
thinking the same every time. but it keep being so cool
Khewl
The fact that he could see the nails in the walls is really cool!
no, is not "really cool" it is : "woah, that is so cool”
Couldn't he just use the same magnet to feel the nails?
I actually need to mount stuff on plaster wall, and this could be a really useful way to find the metal structures behind it
@@ThunderMuffinMan Sure, but this offers a striking visual representation, rather than a force you need to feel.
@@ThunderMuffinMan yeah he wanted to demonstrate the induction das all
The timing was perfect I was just playing with magnets when This was uploaded
Not a coincedence. That's Alexa/Siri listening 😳
@@ZzzRoofus Siri isn’t in control of when the Action Lab posts though, you could say that was the case if the video was *recommended* to this person while they were playing with magnets but that’s not what happened here. The coincidence is that the action lab actually *uploaded* the video as this person was playing with magnets 😝

hi
I'm always surprised as to how his garage looks so white and clean after all these years of doing weird experiments in there. I mean the garage door, the floor & walls look almost pristine new condition after all the burning, combustions, and general banging stuff around in there...kudos!
"General banging stuff"
@@itsthepanshu maybe that's what kept the garage all white and soft looking....
Didn't he have the whitest paint?
Just add a layer after each experiment. Presto! Pristine lab every time!
He's how2basic
Clearly the walls are made of cuendillar.
I love how you explain everything in a simple manner.
Because he's a simple man. Maybe you two vibe that way 😜
not an explanation, a description big difference
It is very interesting that radio signals visible like aurora above sunspot. Alfven hypothesized that sunspots, whose whirlpool-like rotation had long been known, can act as generators, producing powerful electrical fields as they twirl in the sun's magnetic field. Accelerated by these fields, electrical currents shoot out along the sun's magnetic field lines, heating the ions in the sun's atmosphere and making them glow brilliantly-almost a solar aurora.
The sun may turn into a red giant, and black hole may evaporate away due to Hawking radiation after 10¹⁰⁰ years, but my man will never run out of ideas.
And that's why I love this channel.
i love how completely irrelevant the first part of ur comment was to the last part
The sun will not turn into a black hole. It’s not nearly massive enough.

@Shiva Giri oh I guess you can comment in Spanish to answer me. Vamos, haz un comentario que esté bien, lo leeré
sometimes i forget how cool you are and the cool videos you have been making consistently for the past 3 years and more. thanks for putting the physics from lectures and notes into visual demonstrations!
Just so anyone can understand: There’s a difference between bending a light ray without a change of medium (n1=n2) as in actively changing a photons path by some force acting on that photon and changing the path of particles with light reflecting on them. Therefore you’re not bending light in the literal sense. The only force that can do that is gravity.
No... Gravity don't, it's just Einstein's relativity which causes that phenomenon.
Can't wait for a video title about "How Fire gets its shape" or how much of a sphere the earth is
It's not sphere...earth has elliptical shape
Because of gravitational and centrifugal forces
@@noneofyourbuisness6969 It's only a 0.3% difference in length between the poles and the equator, it's close enough.
@@Samu2010lolcats I did my research...
@@Samu2010lolcats You can also be correct.
I read once that a golf ball scaled to the size of earth would have much larger mountains.
Love your channel. I wonder if you've seen Kenneth Wheelers work with magnetic fields. He's probably one of the worlds leading experts on magnetism. Literally wrote the book on magnitism. He makes Ferrocells using optical flat glass. I made one using window pain glass cut in 2 circles. Its so neat to be able to see the field in this way.
This has been by far the most interesting video to me, thanks for making these kinds of videos. Not everyday we see someone do this let alone get famous with it! Keep the improvement going!
Great job!!!! Another interesting and informative video! I love when you put the paper on the wall to find the nails. Thank you so much.
I like the way he says "You..." as if I'm following along at home with my own ferrofluid and LED lights - just like this is a cooking show. It makes me feel like a could be a garage physicist too.
Same
This was a mash of theoria apophasis and braniac. Thank timm vanderelli for this invention.
ruclips.net/video/RMToXnxDgg0/видео.html
@@dark243stone Theoria apophasis is silly word salad pseudoscience.
Ferrocell does not show fieldlines, or anything else relevant. Pattern is produced by reflected light from magnetic particles in ferrofluid. Magnetic field affects their orientation and thus pattern, but you cannot easily deduce any magnetic properties from it.
AB science (ruclips.net/video/pc9ghVd1rsw/видео.html) has good explanation video about it
What are field lines ?
@@klausluger7671 the light reflects off of the nano scale iron yes, but the form they take are clearly dictated by the magnetic field? And the change of shape as the magnet is moved? Everybody is so quick to jump on the maths and physics descriptions but not so quick with explanations.
@@dark243stone Just a way to visualize underlaying vector field. And vector field is a way to describe magnetism mathematically. wikipedia will tell you more if you want deeper explanation
Your videos lately have been really great. Keep up the good work.
This is the best channel ever.. ever since I saw your vid on Facebook I started foloowin you wherever I can find you.. you always blow my mind with these amazing experiments
Magnet: I saw some aura around me🙄🙄

@@yaku_8856 yeah, hahah
@@yaku_8856 Just abouta say that
@@Hi-sg4wt 😄
Man you just keep nailing it! Nice work sir!
reminded me a physics experiment back from highschool. the setup consisted of a glass sphere with vaccuum inside, as well as a piece of coal in a circuit acting as resistence. over it was a cone with hollow tip, so when the coal was electrified, it generated a beam of light that was actually purely negatively charged.
The real show was when two hugeass electromagnets were also powered up, which ultimately curved the beam of light in the vaccuum, bending it all the way into a coil, if my memory didn’t exaggerate the visual in the last 20 years.
I thought it was going to be that, but still thanks for rehashing those fond memories from the lab. There probably is a standard name for this experiment device and you - and anyone else reading it - probably knows. but given your content, I’m sure it would be cool both for watching and creating.
Question ⁉️❓❓
Can you put a magnetic ball into a hollow magnetic sphere?
Please do an experiment if possible ☺️
I hypothesize the ball would fall to the sphere's inner surface, pointing toward the ground.
Ken wheeler has been doing this for a looooong time with his ferro cells over on his channel.Theoria Apophasis.
I was looking for the Ken Wheeler comments. He's done a LOT of explanation. I understand some of it. Lol
Seriously this is awesome experiment, it helped me understand the concept more deeper
Thank you so much for this path light demo
The Action Lab, the only RUclips channel which actually does what it says in the title...
I am fascinated with butterfly flight - especially when they fly against a 20 mph head wind. This video was a great source for renewed visualization.
Awesome job on this video. Great way to present magnetic fields
Genuinely one of the coolest things I've seen!
What happens if you feed ferrofluid to a venus flytrap?
Or water some celery with ferrofluid?
Ferrofluid is oily. It won't water the plant.
@@kofeaclarrinfea9877 water-based ferrofluids exist.
Can Magnets bend laser light....?
_All of your vids are so much fun as well as informative._ ❤️👍
You are getting better and better in explaining stuff, nice work man!
Edit: and the experiments are amazing.
You should have credited Theoria Apophasis for this! This is his work you're replicating.
But wasnt it Timm Vanderelli who created the ferrocell? Genuine question.
@@mtndewv trademark link from ferrocell(dot)us website say you're right, but has Ken Wheeler acknowledge on the site.
@@mtndewv It's not about giving credit for the ferrocell. It's about giving credit to Theoria Apophasis who created this set-up to see the magnetic fields so beautifully. He's the one who showed on his RUclips channel how to make this, how to mix the ferrofluid with the oil, placed between glass, and then putting the LED light all around to show the field-lines as magically as it does. Action Lab clearly saw TA's vids and decided to replicate them, and so they should, even just out of courtesy, acknowledge him and his channel.
There is another channel called AB science that has recently stated that Ken has it all wrong and will be releasing a video soon to prove it. ☹️ hope he’s wrong 😑
@@OrphanRed but that will never happen, because he's not part of the tribe of modern science believer, at best the inventor could get mentioned at the very least.
"To be clear, it does not show the magnetic field lines,"...........WRONG
First off, don’t type “WRONG” unless you’ve got the correct answer and want to share what it is.
Secondly, it doesn’t. Magnetic field lines aren’t physical and you don’t see the field lines. You can see the actual lines, but you can see where they are.
Like putting smoke into the air. The smoke doesn’t make the air visible, but you can see how it’s moving.
Edit: I just checked this guy’s channel out and boy is he full of himself. I’ve never seen someone so confidently wrong as this guy who wasn’t either running a cult, or living in Mar-a-Lago.
For the record, ken is just thouroughly aware that he's a genius. Not the same plane as trump who believes he's a genius but hasn't the brain capacity to back it up. Js...distinct difference from the mar-a-lago
Rebecca Freeman he might truly believe that he’s a genius, but I’ve seen a handful of his videos and I can assure you he is not.
And how does a genius post something so vague and open ended as his comment above without backing it up and educating everyone else? Dude loves to talk so I know he’s got the words.
You know why he didn’t back it up? Because he’s not on his channel. He’s out here in someone else’s backyard speaking out of his ass and he knows if he tries too hard he’ll get ridiculed and the people who watch his channel will see what a fraud he is.
@@rdear lol Ken Wheeler is a genius regardless of his personality.
forma3 He may be, but that’s a claim that needs to be proven. If he’s so smart, why would he comment that something is wrong but not correct the wrong statement and back it up with evidence?
And if you’re response is that he doesn’t need to prove anything, why did he go through the effort to call someone else out?
Incredible! Very cool experiment.
Super cool video! It would be interesting to see what the ferrofluid alignments look like when you try to touch the same sides of magnets together, like N to N, or S to S? and maybe see how the magnetic lock works on it too (the one you had in a previous video that can turn on an off by turning the alignment of two magnets together)
I would love to see that as well! Great idea!
Great demonstrations.
Honestly, best video yet :)
Outstanding! I will be trying the ferrofluid trick!
Thank you, for all your hard work and sharing with us all!!
Always informative and interesting! Thanks.
your videos are gold dude! thanks for doing it!
This is an outstanding demo. Never saw magnetic field lines this clearly.
I'll say your DIY glass contraption is a much better and much sensitive tool. Awesome work!
This is one of the best video on this channel
Very cool! Thanks for sharing.
I would love to see the research and experiment part of your videos behind the scenes. Also I wonder if you have students as interns or assistants. That would be really cool for science enthusiasts
ruclips.net/video/RMToXnxDgg0/видео.html
This person did it first.
@@B.V.Luminous Doesn't matter who did it first. Not every single person is going to see their video. However, the Action Lab can teach it to many more people. They can do the same experiments over and over again and get the same results, that's the literal premice of how things are proven in science.
amazing stuff! Love the "nail finder"
Very cool experiment
This is a call to action to make this amazing model better
I have to say, you literally inspired me to think of fusion in a different way. At least with magnetic fields and just using size, scale, speed, and stepping it up with a mechanical advantage (gearbox)
Very cool. Thank you as always!
The Action lab favourite line
: Thats so cool😀
This is really cool!
Probably the BEST explanation for magnetic field!
That is awesome. Stack layers of glass and ferrofluid for a 3 dimensional representation using "slices." Color the slices to to be able to distinguish the different depths by having each layer use different colors of LEDs. Also try a anti reflective coating on the top glass for less reflection.
Been waiting for someone to do this, thought about doing it myself, was going to cut a cylinder through all sheets and then drop a magnet down the hole and record it. Using different leds likely wouldn’t work well though so not sure if much point.
Moving magnet would be interesting with that type of setup.
that was very fun to watch!
One of the cool stuff you made this year so far.
❤️ from 🇧🇼 Botswana
Wow the light one was very cool
Always impressive. Also cool that you're not actively endangering yourself in this one too lol
nice to see you followed up on my recommendation to explore the ferrocell.. for a more permanent device you need optically flat borosilicate glass and make it sealed..
This guy never run out of ideas
DUDE!! You made my jaw drop with that light setup.
This is his one of the COOLEST videos ever!!!! 🔥🔥
Ok so I just want to point out that this is the best way to find studs in a wall that I have seen yet. I love it.
Best magnetic field visualisation ever!
This is so fascinating it made my jaw drop. I just sat there, mesmerized, like NO WAY...
This is really awesome! 👍👍👍
Those magnetic lines were absolutely gorgeous. 1000 times better than those crude drawings in my physics textbooks. Very cool. Very cool. Thanks ❤️❤️
2:06 Magnets are so cool! I received a magnet set when I was a kid for Christmas one year. I was always experimenting with it. In fact, I snuck my magnet set outside and often took it to my neighborhood playground. I waved my magnets over the sand and was surprised to see these non-living "black things" jump up out of the sand and cling to the magnets!
I didn't find out they were iron filings until I was a lot older. I just thought they were magic little creatures (I pretended they were alive) that needed to be rescued from the sand. Lol I didn't keep them because I didn't want my mom to know I took my magnets outside. She never said I couldn't, and I never asked. I just assumed I'd get in trouble. 🤔
Anyway, when I was an adult (or at least pretending to be one... haha), I took a newly purchased magnet out to some sand at a local park. I wanted to show my daughter the same "magic" I experienced. Unfortunately, this didn't go well. There were no magic beings waiting to be rescued from THIS sand!! How disappointing. So, off to the internet to try to figure out why they weren't there.
From what I could find, iron pilings are sometimes found in beach sand. I'm assuming, then, the local park didn't use beach sand. Or, perhaps it was filtered to remove such "imperfections" like iron filings. 😡
I was truly upset about not being able to share this magic with my daughter, so I purchased iron filings online and placed them in Dollar store sand for my daughter to find. Lol I don't have a technical, logical, scientific mind. I'm more of the imaginative type. But that's what makes magnets so appealing: they "attract" both left AND right brained people. 🙂
That's the most amazing video on magnetism I have ever seen
Most excellent, as ever!
Thanks for the educational content.
Best channel for experiments 👍⚡
That was a useful video!
Nice! You found the fero- fluid magnetic 3D viewing glass! And a variation idea about it that I hadn't seen before! Cool! You do realize I hope that it actually shows the energy vortex and direction of spin on north and south poles of the magnet.
That is really cool!
Just looking at those magnetic field lines is soo damnn satisfying
I LOVE this channel.
TIPS: Spraying material will produce a smoother surface than wiping, plus topcoat the ferrofluid with clear acrylic lacquer and it won't oxidize.
super cool, it would be interesting to see the magnetic lines in a picture of single magnets, example, take a picture with only the cilynder, a picture with only an sphecial magnet, etc. Thanks for sharing, awesome work.
look for Theoria Apopahsis he did loots of video on the ferrocell
I love your videos, your child like enthusiasm brings me back to my childhood. And the wonders of science so thank you
this guy does have some really cool stuffs to watch
Whoa! That looks really cool. Would like to see this with magnetic breaking. Might need slo-mo, though.
That was great to see a magnetic feild in real time. I wonder if can you make sound waves visible?
That nail trick looks like it would work to find stud locations in the wall where sheetrock is screwed to the studs!
That last little hard about finding nails in the wall would make a great stud finder!
That is so insanely cool
Looks awesome.
I am only 15 years old but I love to watch your videos , thanks for giving me knowledge👍
Visualization of magnetic field is really awesome
He is really too smart ... finding iron nail with magnetic film is clear expression of his thought and concept clarity ! .. Kudos!
