Someone please help, I’ve been stuck in a loop with this video and the veritasium one for 4 years
me too
Lol noone can help u
@@anand.suralkar I can
@@pr1m3rI assume u r Indian by ur name. It's simple, take the 2nd pu ncert physics n chemistry books or hc verma books, this video has the exact explanation which I read in those books.
Maybe this is what black holes are made of, a circular youtube link topology (btw click here to know why black holes can also be magnetic)
- How do magnets work?
- Oh, they're just a bunch of tiny magnets
Magnets all the way down
Moving charges
Magenets work:One part of the magnet is positively charged (more protons in compostion because when we see a material in microscope we notice the atom that is composed of neutrons with no charge electrons negatively charged and protons positively charged also the nucleus of an atom is composed of neutrons and protons normally and the electrons in orbit to the nucleus.There are only two type of charges in the universe) and the other negatively charged (more electrons in composition).Same charge push each other while different charges pull (attract) each other.
the video is more about why some things appear to be magnetic while others arent
@@jurgensala7181 Nope, that's the electric force.
After having taken some advanced physics courses in uni, I have a much greater appreciation for these videos and I appreciate their very clear explanations.
Yes, but for the rest of us.... I literally had to pause video every five seconds in some sections to digest what they just blew thru...
me too bro
Yeah us high school students struggle with keeping up but I'm usually able to understand moat of they say.
College is a scam, my guy.
Yes ❤❤
Remember Jesus loves you so he died for you because he wants to know you❤Repent, God bless❤️

I want to cry... I've been searching for HOURS how the heck are magnets working on an atomic/electronic level. Other videos usually brush the how and the why off but yours was precise enough for me to have a clearer understanding of the phenomenon. I'm going to devour your other videos.Thanks, from France
i'm having the same problem, even after watching this video my brain kinda wants to grasp how magnets work, but the concept still feels confusing, lets see if another couple of hours make me grasp how magnets work
I believe that the atomic plate alignment within the Rock allows the electrical charge in the air 2 pass through it. This alignment in the rock is a path of least resistance for electricity in the air. This would create a denser atmosphere on one side where the electrical charge is entering the rock while at the same time creating a lesser dense atmosphere on the other side as a vacuum. These density changes in the atmosphere around this Stone because of the absence of electricity in water causes them to be able to push against one another even though they are not touching. The atmospheres around each end of this magnet depicts how it will interact with other magnets. That's my theory.
Once I start watching these videos, it's hard to stop.
Stephen Zogas I have Machines Theory exam in a week and can't stop watching this videos. T_T
Nice
Noice noice
One could say , there is a certain attraction
That is what we call momentum
Those days when veritasium and minutephysics did collaborations.
Tell me about it
yeah tell me about it
Yeah, tell em' bout' it!
Yeah tell me about it
Wow, FINALLY someone explained this in a way that I could at least begin to understand! You guys ROCK! (have you gotten awards yet?)
I'm with you, this finally totally explained magnets to me, right up to the edge of our knowledge, A to Z. Brilliant. One of my favorite science videos ever.
one of the best videos on magnetism ever. everyone talks bout how magnets work but no one tells why magnets work? like that is the fundamental concept that if uncleared poses so many doubts , thanks for this video it cleared many doubts ;)
I liked how Henry drew the electron shells. He avoided the stereotypical and incorrect depiction of shells.
Yeah
I know it's been 3 years, sorry if you don't give a damn anymore but... Being a chemist myself, out of curiosity, could I see an example of such "incorrect" depictions? Thank you!
Yeah, Bohr model triggers people.
@@bennemann Three years later, he’s talking about the atom model which uses concentric circles
I watched it today for the second time and this time I was trying to grasp it in order to teach my class. I realized how each diagram that you drew speaks so much and while trying to learn everything you had to say I ended up having more than 4 pages of notes and so much of amazing magnet's knowledge. Thank you so much for this :) I am not sure if you will ever read this , but you truly inspire brother and I feel like pursuing physics more and more
I wish they taught us magnetism this way in our schools
you learn more solid things on youtube than books
Well, its school. So it would be boring as fuck
Watched this in physics

More like “C SAUCE”
Puppy Puppington huh?
Absolutely awesome as ever! This is one of the clearest (it's still a bit tricky for me) explanations of why you can magnetise certain things and why some are naturally magnetic!
This video reminded me a physics exam of my student. I helped him telling that when the electrons are aligned in a magnetic material in the same direction, the material becomes like a self-wire in which electrons flow in a preferential cycle. So, this material becomes an electromagnet with no need to pass any current through it. Such a good video reminding me also a bad moment: He didn't pay me for the last two classes leaving no trace behind:))) Good work bro!
2 of these videos are more science than I will ever learn in school

i have no way to express my gratitude- just... THANKS DUDE.
i had been surfin the web for hrs for someone that would explain me
you earned a like and sub
THANK YOU!!
I've been researching chemistry as a hobby, and jumping around has led me to the functions of atoms and the structures of unit cells, this feels like a puzzle piece that connects the two. I see it so much clearer now, thank you very much.
ICP should watch this video
fukin magnets how do they work
+poper Pooper Actually It wouldn't help since nobody really knows! ICP could have been referring to protons or electrons as the "fuckin' magnets", and no physicist would have an answer for them!
+poper Pooper Well... most of them are dead now, yes? I don't recall them having great fortune after that song/album. Then again, was never a fan anyway.
+fuflang thats the point. its funny because not knowing something doesnt prove anything. its like saying how does gravity work? see miracles are real! we know how magnets work, just not why.
Fuckin logic; how does that work?
This is one of the best explanations of how magnets work that I have found!
This video really helped me understand magnets in a way I've never before. Thank you minute physics, thank you veritasium. You both really are amazing.
Watching those two videos, I finally understand how magnetism works. *My life is complete*
Watching the two videos, then, electromagnets are explained by special relativity and permanent natural magnets by quantum?
3:16 I said "Why is Helium next to Hydrogen?"
Probably to show that He and H are next to eachother in that they both only will fill the 's' orbital.
EpiCuber7 you replied to a 3 year old comment thank you for that
@@RSPikachuAlpha :D
These videos are a fantastic demonstration of how quantum mechanics and special relativity both really apply to everyday objects and concepts that everyone is familiar with.
00:59 vsauce style
interesting re the Chrome. I recall back in the 80's and even 90's when compact cassettes were also used as a recording medium for music, the better recordings were done with Chrome Dioxide tapes which had a wider dynamic range, though the energy required to record on them needed was higher, only recorders with the CrO2 Bias function could do that.
Short answer: "No one knows, that's just the way the universe works."
Honestly, magnets are fascinating. If you have ever spent time playing with a magnet experimenting with it and what it can do, It's almost like something out of a science fiction book. Many things can be done with technology nowadays. But this is a simple material that occurs naturally that creates an invisible force that attracts and repels. It leads you to wonder what else out there exists beyond our comprehension.
watch the veritasium video in the description, magnets work because of electric force and special relativity, we understand magnetism, haha but yeah electric force is a fundemental force which just works because it works.
@@studyhelpandtipskhiyabarre1518 this video is about permanent magnets while the Verituasium video is about magnetism due to movements of electric charges.
@@dimlighty which is the same effect, because the tiny magnets explained in this video also have moving electric charges
They just explained it in the video?

TECHNICALLY since we're in a physics class anyway the wood next to the wood does actually do something just not noteable because all things react gravitationally with eachother no matter how small and insignificant it might be
Gravitational force is the weakest force out of the four.
In7enseCA But that doesn't justify us oppressing it CHECK YOUR QUANTUM PRIVILEGE!!!
Kent I'm just saying that the gravitational force is extremely weak
In7enseCA I was being sarcastic and making fun of politically sensitive people :P
The woods are not getting closer because the earth’s gravitational force exceeds that of the woods’.

F@#$ing magnets, how do they work?
@@eclipse369. That's just another 2 descriptions. How do the work? All we can do is describe phenomena and give them names. At some level, what is simply is.
I would love to see Derek's children react to this video when they're teenagers
Well, thanks a lot Derek and Minute Physics-like, honeslty, I am currently a student who is in 12th, and this was something that just made me visualize very vividly what all I was studying. Like, I could understand that, but this gave me the FEEL of the Concept. So yes, thanks from the Bottom of my heart!
+MinutePhysics That was a terrific video! Thanks so much for posting!
Finally a guy that explains physics simply without big grammar but in simplicity,thank you , you don't know what you did for me.
I don't know how to thank u guyzzz..... I've been searching for such video with such superb and clear explanation
See this is why I love quantum physics and general relativity, its when you understand the physics is when your head starts to spin, not when you don't understand it ;)
Amen, brother :)
But which way does it spin relative to the person's head next to you and does that create a magnetic field or just an anomaly in the space/time continuum?
With you
InsideOfMyOwnMind It will spin in the opposite direction regardless of how far away they are from one another, assuming the two heads are quantumly entangled
What is Quantum theory is
While MinutePhysics truly is remarkable and I did learn a lot from this, I’m pretty sure I’ll forgot this soon due to the RUclips Effect. So I hope I can do all of us a favour( including myself) by giving all of you a summary of this video. To make is relate as much as possible, I did it in the manner of question-answer:-
THE FUNDAMENTALS OF MAGNETISM:-
Required Knowledge:
1. What are magnets?
2. Behavior of magnets?
3. A basic(even if it may be limited) understanding of quantum mechanics.
Summary:-
Magnets behave as they do due to the fact that they extend magnetic fields out beyond the object.
Question 1: Where do magnetic fields come from?
Answer: Magnetic and electric fields are different aspects of the same thing( two sides of the same coin; especially as a result of an ingenious solution in special relativity[in Veritasium’s video]) i.e. they can be transformed into one another by way of motion causing electric fields to turn into magnetic fields for moving charged particles.
This explains many things we see in nature but something is still not quite good in our understanding.
Question 2: Iron and other metals are pieces of metal, what causes them to behave ‘magnetically’?
Answer: This is the first part of quantum mechanics helping us. Atoms have electrons moving in them. This is a particle with a property known as intrinsic magnetic moment which is a technical term for explaining that particles also behave as very “tiny magnets”. The reason behind why this happens is unclear(we don’t know it).
Atoms consist of protons with electrons revolving around them. So we have another question from this observation(a subpart to this the answer of this question).
Question 2.1: Are atoms also tiny magnets?
Answer: Yes. Atoms generate magnetic fields called orbital magnetic fields. But these don’t contribute due to the overall nature of magnetic fields in an atom. This is the second point where magnetic fields help us. Electrons are described in 4 sets of ‘objects’ in quantum mechanics-Principal shell, angular quantum number, magnetic quantum number and spin. We are interested in the last 2 for answering this question. We can use these 2 ‘objects’ to justify reasons for atoms
1. In filled shells, electrons move around in all directions causing current to cancel out thereby not generating any magnetic fields.
2. Electrons come in pairs(Pauli Exclusion Principle) with their intrinsic magnetic moment(remember ‘tiny magnet’) pointing in opposite directions( have opposite spins) thereby cancelling out each other.
But this is only the case for fully-filled shells(having electron pairs and opposing spins). In half-filled shells, electrons are unpaired. This intrinsic magnetism in the outer shells which gives atoms a majority of its magnetic field.
But chromium(having a half filled shell) isnt magnetic. This is another question!
Question 3: Why isn’t chromium magnetic?
Answer: This is due to the fact that there is a bigger scale to look at when considering this special case:Crystals. When atoms get together, they can either align their magnetic fields with each other or in the opposite direction. This is decided by whichever is the most stable.
This gives rise to the final piece of information to understand the nature of magnetic fields.
Question 4: Isn’t is possible for a group of atoms to have a set of atoms lining one way and another set another way?
Answer:Yes but one can apply magnetic field/force/pressure strong enough to create a sort of control over the other group of atoms causing sort-of magnetic behavior.
Conclusion(TL;DR): Magnetism is a fundamental( and beautiful) result of quantum mechanics.
This was a summary, I hope it helped you all out. If it did, I’m happy. But you can make me ever more happier by answering this question. Something I got out of natural curiosity.
Question BONUS: Is the behavior of magnetism and the intrinsic magnetic moment a reason for opposite spins and the existence of the Pauli Exclusion Principle?
Thanks!

Electrical fields and relativity.
Or in other words: They just do
all just observations sadly, but we still have not observe the actual phenomeno
this video was more gee-whiz obfuscation than explanation.
It's funny, they actually taught us in middle school the sequence of how electrons occupy the different shells in an atom, but they never told us what it means.
COULD YOU MAKE A VIDEO ON MONOPOLE MAGNETS ??
Amal Jood Ha ha ha. Good one.
sucik man If you can read this and understand why the electric and magnetic dipoles are different, you will be halfway to a physics degree.
en.wikipedia.org/wiki/Magnetic_monopole
+sucik man An unpaired electron, of which the magnetism of permanent magnets arises, has its electron magnetic dipole moment parallel with its intrinsic quantum mechanical spin. I.e. there is a direction, i.e. it is a dipole. Not a monopole.
Monopole magnet do exist??
You make me want my kids to rapidly learn English so they can enjoy this type of lectures. Sooo appealing and easy to understand.
When Veritasium appeared, i was like: ,,shit's gonna get complicated!"
3:50 - Is there another video expanding on what determines the energy required for atoms to line up in consistent vs. alternating magnetic fields?
I can assume that it has something to do with the shape of a molecule (like O2, rather then just O - if metals even has molecules); or, with likelihood of a metal to make molecules with any other atoms to cause some impurities in crystals and ore (like oxides, etc.).
So, the crystal structure is geometry-dependent, is what I'm saying; and that geometry is surely molecular.
knew i could cuont on you! i literally said 'veritassium must have covered this'! & here i am. w/more answers.
Loved every second of this Video! Magnetics as an expression of Quantum Mechanics was just the stepping point for me to start to appreciating this kind of observable aspect of what, to the Layman, can be very abstract concepts. It can feel at times as if we are just to take it on faith that we are to accept Scientific Consensus as true, these scientific principals which can feel (at times) counter intuitive to our relative experience of the world as we observe it.
You guys make physics so much fun! Love your work ❤️❤️
MIRACLES
0:59 "or are they?" and you hear music from Vsauce..
Excellent video. My first course in electromagnetism used the popular textbook by Purcell which first establishes electrostatics and then shows how magnetism arises from special relativity and the fields of moving charges. All well and good, but it glosses over the fact that not all magnetism is explained this way, and that quantum mechanics is involved at a fundamental level in explaining the intrinsic properties of magnetic materials.
music is a lot like love its all a feeling and it fills the room from the floor to the ceiling i see miracles all around me stop and look around its all astounding water fire air and dirt fuckin magnets how do they work?

Hello adventurer.
Welcome to honeywood
I have an odd question. If I had a perfect vacuum and I wanted to create an atom of Hydrogen. What would I need to do in order to create it ,inside that vacuum? Like what steps and energies would I need? How could I construct it? Imagine I have access to anything I would need, maybe a star or an unlimited continuous power supply as large as it needed to be, the ability to manipulate gravity and space/time, and as long as I needed.
I think knowing the answer to this would really help me understand what matter is. I have always heard it's
"frozen energy" yet, in my mind, to be frozen means to remove energy. Which makes me wonder if it isn't really just super saturated space. That is to say, a specific amount of space that was forced to contain the most energy it could, at which point it some how solidified and then stayed in that state. Then by adding a specific amount of electrons, you then change it's properties and make up.
Any insight into this would help me out tremendously. Thanks.
Ok, it depends how fundamentally you would like to start. You could just recreate a minute big bang.
But let us do it slightly differently. Let's say you were to really start with a perfect vacuum and just some energy in the form of the ability to create photons with arbitrary energies.
So you could simply create photons with an energy of more than 1022 keV. These photons can decay into electron-positron pairs. However, it is not that simple: they cannot directly decay into those pairs ... they need to interact with something else while doing so (for momentum conservation). To simply creating a single of those photons would not work. One should better create a whole bunch of them so there are always several electron-positron pairs around for other pairs to be created.
You could, for instance simply shoot these photons towards each other (that is also sometimes done experimentally in laboratories).
So now you have a bunch of electrons and a bunch of positrons. But they'll annihilate. So to have actually something left, let us create an electromagnetic field, that moves the electrons to one side and positrons to another. Remember that an electromagnetic field ist just photons. So it is covered by your superpower ;) (in the lab you usually use magnetic fields instead by using strong electromagnets ...).
You can do exactly the same with protons. However, the energy of the photons will have to be a lot larger (at least around a few GeV) and you'll create a whole bunch of other (unstable) particles in the process. Afterwards again: split the protons and antiprotons up so they don't annihilate.
Let's say after a while you have isolated one proton and one electron with your electromagnetic field. Then you simply let them approach each other. As they are attracted to each other, they'll close in and at some point the electron will get bound to the proton by falling into one of the discrete energy levels it can take around the proton and giving of it's excess energy in the form of a photon.
At least that would be one way of doing it today in a lab with the rules you provided ;)
Does that help a little?
Does that help? That is more than helpful, that's exactly what I was hoping for. A step by step guide more or less explaining the processes and how they matter to the overall system. Thank you so much. That had to take a while to type and even longer to learn everything required to state it. That was a concise and understandable explanation. Thanks again.
Corey Carnes
Wow, you are welcome :)
I'm very happy that I could help you so much :)
***** Hi, I'm sorry but i'm really bad at science. however from your explanation, are you saying that the essence of matter originates from light energy?
Edward Kenway
Hm, I'm not sure what the "essence of matter" is. Do you mean: the origin of the particles we observe around us?
Beautiful collaboration...God bless you guys
This doesn't explain what magnetic fields actually are. All we know is that magnetic fieds are caused by relative motion of charged particles.
Problem is, that electron clouds can't be considered as particles moving around the nuclei...
exactly
@@AstralTraveler why those?
@@sumedha1051 because they remain in superposition and their motion is not determined
@Robin Hack sure - that's why electron clouds have to be described in terms of probability, which is distributed in time and space - and not in terms of particles moving along determined paths. However in an electric current motion and spin orientations of electrons are in fact determined by the placement of electrodes - that's why a magnetic field is induced around a wire...
Confused here: veriphysics x minutetasium ?! :P

filonin2 its related... But ..theoretically yes...
We’re one step closer to making a TARDIS!
Wow! That was really well insight into magnetism that I always missed in physics classes.
Thank you!
But I still have a question:
why do both poles (S and N) pull in other metals?
I mean, N and S are opposite poles, that's why they attract each other. And when you put N and N together, they push each other as they're same.
So, shouldn't S pole push away foreign metallic object while N pulls it in?
Still, when you put not magnetized metallic object to S pole side of the magnet it still pulls it towards itself.
Why?
Have I missed something (I refer to physic explanation)? Or is it another unsolved mystery of science?
Because they are ferromagnetic
These videos were amazing and are amazing 10 years ago and even today ❤

0:58 Vsauce?
1:58 I thought objects with mass and energy attract each other gravitationally because they curve space time.
That's right, but he's talking about asking "why." Like, WHY do massive objects/energy seemingly bend spacetime at all? More of a philosophical question.
But "why" in the sense of "how" is what science is for.
So... a consequence of the distortion of space-time as a result of the unequal distribution of mass...
And then... what then would happen in a universe where mass was distributed evenly?... looking at the answers on quora there's a lot of speculation but no real answers...
How long on average does it take to draw all the diagrams for an average length Minute Physics video? Do you ever make mistakes and have to start again?

why does chromium find it easy to align in an opposite way while iron finds it easier to align together? (sorry for the bad vocabulary...sadly not able to find the ryt words now)
+Aman Vernekar Like they said, it's about what is energetically favorable. The same question also comes up when building individual atoms with electrons of different spin and angular momenta. Look up Hund's Rules for that
DANGJOS why is it energetically favourable was my question
Aman Vernekar Oh I'm not sure. I work in a condensed matter lab so I can ask one of the graduate students or Post-docs if you want. It could be that it just is that way
DANGJOS oh...it would be really nice if you could ask one of them.
Thanks for taking interest in this
+Aman Vernekar Alright, I'll ask the Grad student I work with, and if he can't tell me I may ask the group leader (the Professor).
