9:35 _"Click like if you didn't dislike the video"_
Got me thinking for a while
*Planet Purgatory* yeah thanks for explaining, I understood it better now :D
Double negatives FTW.
*Reverend Jynxed* yea boiii
Lol, this is how a person with a high IQ gets subscribers and likes. :P
"Please click subscribe if you dislike *not* watching my videos."
Yeah, it got me thinking, too.
I think the next step has to be an electromagnet
The part at 4:40 made me think of a "how many jelly beans are in the jar" experiment, where they had a large number of people guess how many beans were in the jar, and the guesses, when averaged out, were startlingly accurate.
That "Hi" at the beginning made my day haha
I wish I was that ATTRACTIVE...
same
booooyouplaygrowtopiahowsurprising....
Bruh chill
Rohit Bhatia I do admitt: I am so, sooooo, glad that i am NOT that attractive! UUUGGH; What a hell it would be, with all the trouble-makers in society, who needs (or wants) extra stink to attract attention of such shitty people?!?? Having magnetos superpowers would/could be cool, star Trek technology, or Q's "imminent powers that be", would be really neat. I think that after a short while, it would become boring and uninteresting. Until then: just too damn dangerous! I know that there is a God that prevents us from attaining such superiority! 😏
Fuck you
oh wow thanks
Congratulations! 😁✨
Well done
@Kevin S you're missing google?
.
great geuse!
Another terrific video, as always. Thank you for a very enjoyable production!
Your videos are great, i love how you work hard to make your videos with quality, even adding a subtitle!(which for me is really useful as english isnt my primary language so it is a bit harder to understand people talking it). I love how you also dont make popularity as primary goal, instead of asking for likes in the beggining of the video, you say "Like if you did like" in the end. That is really nobel. Your channel deserves much more.
Nobel? That's the name of a prize (named after Alfred Nobel). I think you meant "noble". Unless you mean that he's suited for winning a Nobel prize... I'm not an English speaker either, and I also appreciate the subtitles.
@@GRBtutorials i meant noble, i probably miss clicked it
Flydrop88 Yeah, well, apparently that’s a common mistake. Even Cody’s Lab miswrote it and later corrected it (it appears wrong on the sub feed and in the email)
Now time to get 2x 200w by 50h magnets ;) that would be a beast and would be very interesting as I think it would be the same area as the other magnet but 1 is wider and the other taller. Would love to see the results vs them. Please magnet company send Mr Brainiac another magnet.
Still love your videos after well over 3 years of watching them :P
Also still hoping for more elements vs magnets videos :D
Some interesting scaling there..showing up how the field grows with size..but not directly. Good stuff..TY🙂
Wow, I was not to far wrong with my guess ;). I love this new monster magnet, I am looking forward to the other tests with them, I also am looking forward to see how you can separate them, considering how hard it was to attach them. I adore this channel :)
I wish Jeff was my dad.
it can be done for sure
I'm just thrilled how fast videos are coming out. :)
I dont know what it is about your videos, but i really find them interesting even thou it does not relate to anything i do in real life or am usually interested in =) So great work!
Perfection!!
As always!
This is a fantastic channel. I have only a little experience with these magnets, small ones, and was very surprised at their power and potential danger.
Wonderful experiment.
Always a good day when a new Brainiac video comes out.
I can tell you have a deep respect for what you do, and keep up the good work!! (I am coming up with a "Frankenstein" magnetic motor that we're (hopefully) going to be filing a utility patent on, and I will keep you posted.)
Those magnets look beautiful, great video. BTW the larger osmium sample probably wouldn’t make a difference cos the magnetic field strength of the magnets are the same
Wonderful, an upcoming video about the awesome osmium!
That was amazing I was genuinely thinking you gonna need a bigger house to be able to test this giant magnets , I am sad that I didn't guess the right number but this was a fantastic video as always thank you for all your hard work can't wait to see what you do next PS greetings from Iran
Your guess at 2 m was only ~10% off. That's not bad at all! Did you remember to 'vote' in the poll at the end of the video? Thanks for watching and commenting as always :)
Brainiac75 yes I did vote for number 3 and I even asked the question from some of my friends and we have a competition about who's going to get the correct answer thank you again for all your hard work I can't wait for the next video
Greetings my iranian brother !Lover's of science in iran!
Arminne Ashrafi hi dude 😊
Whoa I just noticed how close you are to 500k :D on the way to a million!
I love these magnets videos!
Brainiac75, thank you so much for including Samuel Li's source code at 5:45.
hello I have a question, will a magnet put on the side of a microwave do anything bad? does it pull the waves towards the magnet or does it just bounce them away? thanks
Im thinking mounting the magnet in a cradle on a ceramic bearing and spinning it near a crt, and other various magnetic objects to see their effect
Glad to see more videos again.
Yay! Another great video!
i love these videos they are very oddly satisfying to me
I really love your work
I meant it when I said it before, and again I still mean it when I say it now:
"You and your precious little videos, aside from being simply brilliant, are absolutely awesome.
Thank you for the well documented and very detailed adventures! (Liked and finally Subscribed too).
I agree that you should not have adjusted for weight because the more material that the sample has, the more material the magnet effects. Similarly to how two objects of differing mass fall as the same speed in a vacuum. P.S. love your videos, keep up the good work! :D
Dude do some fun and cool stuff with these strong magnets
5:20 The Fact it has An effect that Far Away ,,, SO CRAZY !! WOW !
You’re an inspiring teacher!
Wow, this channel is proof that there is always more to learn. You were right about the last video drawing more subs (I was one). Great video! Can't wait for more!
Welcome aboard :) Yep, I also learn something myself by making and researching for the videos. Next video will definitely be learnful for myself. The feedback so far have pointed in all directions - it's not easy to predict with logic how the osmium samples will compare in the setup...
My friend is an NMR scientist, so he's always talking about using 3 or more tesla MRI machines, but those are helium cooled superconducting magnets. For permanent magnets at room temperature, 1.2 tesla is pretty impressive.
How many power will added if you combine 2 magnet is that going to be twice or not? Like two combine d20x10mm vs d20x20 which is stronger?
What gloves do you use? We started working with smaller N52s at work. Tired of getting bit.
Braniac, I have an idea for your giant magnets. As we know, cathode rays inside old TVs can be repelled by magnets. Try to measure how angle can each magnet affect the rays. Thank you...
That'd be a interesting video, I wonder if he has a cathode ray TV, Maybe he could get one at goodwill?
Goodwill doesn't sell cathode ray tvs due to hazardous disposal laws.
he already tested it out with crts
I thought I had seen it somewhere before.
I already know about the dangers of CRTs, It's why I never stand near them and when I do I turn them off.
Nice video, u put alot work for these videos and nice u upload more often
Could you move a droplet of water using this magnet? (Since water is diamagnetic). or even bend water coming out of a hose?
I have a doubt regarding the weight of the magnet, when two nort pole magnet kept in weight machine is different when one South pole and one north pole magnet
Now the real question is : will it create a black hole if you try the same with double 8"/2"
I love your accent, its so calming
The acceleration due to a force (F=ma) and the magnetic force on the sample (~F=mBcos(θ)) both scale linearly with the mass so having more mass with the same distance (constant B) should not change the acceleration.
How'll you disassemble the two magnets?
Do you sometimes test for how much strength is needed to disconnect the magnet from each other?
or is it impossible ?
is it any device avaliable for findling the magneticfield please if you have any information regrading this thanks........
Wow, very interesting!
The effect you are noticing at 3:20 is called the "wisdom of crowds" and was first noticed using crowds to guess an ox's weight by Darwin's cousin Francis Galton in 1907
Yeah they talked about it once on Brain Games (except it was candies in a jar)
Hi, i am into an important proyect and i can't find online stores selling those magnets. How much do you say they cost? I am asking about the strongest, non coupled magnet you have tested.
YES, I knew this would happen
Need to combine the 200x50 to make a massive 200x100. Even better to get that in n52. This channel has my fascination with neo magnets into overdrive. Like you recommend I’m slowly upping my strength. My newest is a 100lb pull n52 block
Does magnetic force depends on the magnet shape itself ? E.g you use 200mm diameter by 50mm thickness , how much distance will change if the diameter will be 50mm, and thickness 200mm ?
A great video would be to do tests with the ferrocell. Beautiful images of the magnetic field. With a magnet that strong you will probably see lots of detail and depth!!
Love your videos
Thank you for doing the research, these giant monster magnets terrify me.
I really like this channel.
Wonderful video.
What a monster magnet!
I can't physically click off of these videos before they fully end, he's just too nice of a person and I feel bad clicking off even at the end
So close!
I actually went back to the previous video and checked whether you had measured from the center or the edge, but then I completely forgot to add the increase in thickness. If I had added half of the 50mm increase in thickness over the single magnet, I would have had a range of 222.5 to 223.5cm. The range was to account for unknown rounding errors in the supplied data.
Edit - I just realized that there is no way that the 175cm data point I used could have been rounded up, due to the original single magnet being measured in 1cm increments. The single 150*50mm magnet may have actually passed at 175.8cm, and still failed at 176cm. I'm guessing it wasn't 175.8cm, since you would have noticed that it was nearly passing at 176cm and likely gone back to check at 175.5cm. I doubt I would have thought of that when I was making my guess.
can you see the magnetic pull on the iron in your blood views as you move your forarm over the magnets? If you stand with your back to magnets and hold the compass in front of you cqan you see the magnet move the needle thru your body. How close and how long can you stand next to it before you think it will start to affect your body or mind?
What are those magnets used for
I know myth busters did a similar test but with your big magnet do you think it would be strong enough to stop a bullet shot past it, not at but past it. Or if it's strong enough to change the bullet trajectory?
wherè do you buy those magnets?
Can someting like this be separated?
Is there any simple method to measure how fast magnetic field travels in the space?
Every time Brainiac uploads, I click the notification immediately.
What power does it take to pull them apart?
There's the possibility that there could be iron impurities from the tools used to work the osmium samples, which could make the 2g a bit more attracted.
Can you make an eletromagnetic one, with equivalent pull force of 1.2 tesla? What voltages, and wires needed?
is it possible to get n55 magnets this big?
5 years later in his current videos these magnets still haven’t been separated lol.
Damn, this magnet is a beast!
Great video as always, thank you!
I only have one question: At 5:47 how do you explain that out of the three people that predicted very close to the result the one that was the closest was just guessing and the two that used the mathematical formula to predict were slightly off? Could they have come up with a method that would me more accurate?
Hi, I'm the author of the comment and program on the left at 5:47. 3cm out of 223 cm is roughly a 1.3 percent error.
The data I used was taken from his previous videos, in which the distances were rounded to the nearest cm. This may not seem like much, but 1cm out of ~1m is comparable to the magnitude of the errors we are dealing with.
I originally used a blind power-law regression to predict the inverse compass distance. Due to the nature of power-laws, this is very prone to underestimation (which did indeed occur in this case). However, after I posted the original comment I improved my method by computing the theoretical exponent for the power regression, based on physical laws (which turns out to be 1/3). Using this refined approach predicts 222.94cm, a much more accurate result.
The improved code can be found here: www.dropbox.com/s/p8n1zyi7nb3h1yi/magnet-prediction-improved.py?dl=0
When doing my original calculation, I didn't account for the face of the magnet being an extra 2.5cm closer to the compass. If I'd done that, I would have calculated 222.99cm, not accounting for rounding errors. In my original calculation, I assumed that the 175cm data point had been rounded to the nearest cm. So I used the smallest and largest measurements that could have been rounded to 175cm, and got the range 220 - 221cm as a result.
Thinking about it again, this is not the type of rounding error that would have occured. 175cm could only have been a rounded down measurement, since he was measuring in 1cm increments.
Using a value halfway between the original 150x50mm magnet's 175cm pass / 176cm fail points, multiplying by the cube root of 2, and adding the 2.5cm from the thicker magnet, gives a result of 223.6cm.
Capitalism is antithetical to anarchy
Well done, Samuel Li and timbargen!!! Might I present the credit to you two!!! 😊
Nice carpet
Hi, It is very nice that you have the patience and the time to perform all of these tedious measurements, I was wondering have you performed any experiments where all of this data has relevance?
No problem. No, I don't use these measurements for anything else than my videos and fullfilling my curiosity about magnets and their performance.
What would be the increase in overall strength if you added another n45?
Hi, I was wondering are the electronics in the Gauss Meter affected by strong magnetic fields? Did you place the meter at different distances to see if you get different readings for the same magnet-measurement? I would like to see a control experiment to make sure that the Gauss Meter is reading correctly.
I haven't tested it. With the price of the shown gaussmeter it better be shielded... It's a pro model and should be designed to be close to strong magnets :) Thanks for watching!
is it possible to de-magnetize these?
awesome! magnets!
would anybody know on how to machine a magnet in the changes they will make to the magnet?
Thank you
Damn I can’t even imagine how you’d separate these! The forces between them has to be thousands of pounds or maybe even tens of thousands
"click like if you didn't dislike the video"
Never heard that one before.
I really like this guy's voice. You have a great voice for narrorating, guy.
I love how your pull tester is made of Lego Technic XD
Great Scott
I feel like it would be pretty neeto to see this thing interact with large plates / bars of copper. Do you have any videos like that?
I would like to see something like triple monolith magnets :D anyways it's an excellent video
Nope my guess wasn't that close before I dwelled to compass test portion
This is like the Marble Olympics but with Magnets.
I also quite often need to bend a saw with a magnet... perhaps I should buy one of these. :-D
Why do they not make this magnet N55 grade Brainiac ??
love your content
Here we go!!!
You should have used a tube placing the magnets repelling each other inside and see what the maximum weight they could hold without compression would have been. You could literally make a magnetic lift vehicle where the cab rides suspended so the passengers feel absolutely no road vibration at all. Lots of applications as well.
i love your videos. i am curious about the repell properties of such powerful magnets. how much weight can they support before touching.
As a rule of thumb: if two magnets with a maximum pull force of 100 kg each is forced together with equal poles facing each other, they will repel with up to 100 kg. In other words they can make up to 100 kg hover at a low height. I may need to make a video about it at same point. Thanks for watching!
