this is so much better than 10 min videos that don't go in depth. how else are you supposed to understand a complex concept like this?

Jason, I am 69 years old man and I have never been so fascinated by science before watching your videos, now I am beginning to understand. You are actually reversing the dynamics of the universe by going from complex to simple. Thanks for offering your talent.

You are "the" genius tutor. No others could be that perfect. I hope we have you in other subjects

If all teachers were as good as you this world would be a better and much different place.

You are a walking.. talking encyclopedia of knowledge. Thanks for sharing

I'm an extreme biology nerd that had trouble during the physics course. I just wanted to say thanks for making this. It was very interesting and helped me get a better grade. I can still proudly say that I haven't failed any classes thanks to you.

I’m 72 rears of age and I loved your presentation. Yes I made it to the end and I’m going to watch it all over again. Thanks for being such an enthusiastic teacher. It’s cleared up some of my own questions and needless to say brought many more questions I need to answer to the forefront… isn’t science wonderful😄😄😄

Sir, you are utterly gifted when it comes to teaching. Thank you so much for taking the time to teach us without leaving gaps in the flow of information, which so often fractures the uptake of information.

I will never look at a solenoid the same after listening to you Thanks for the great info.

absolutely superb lesson sir. You explain things so well and understandable. I am so much more interested in science and its all down to you.

One of the BEST explanations of magnets. & magnetism And it's humbling that we don't know everything... yet. Why from high to low energy? Why do electrons have a spin attribute? More research needed. Hopefully one day, there will be an explanation - Noble physics prizes are waiting.

Jason, I still believe you're the best to explain things despite no one seemingly can perfectly explain to me how permanent magnets work on the subatomic level. The best I could comprehend about PMs is that once you harden carbon steel it becomes magnetic due to the carbon atoms (more the better) locked in its molecular structure that retains magnetism even after removing the magnetic field that created it (hence the reason screws stick to the tip of screwdrivers). This is only valid for carbon steel, not a proper PM magnet, although this concept might apply to them the same way.

Outstanding explanation of magnetism and how electrical current and coils create magnetism. I wish struggling physics and EE101 students everywhere knew this video was out there available on youtube. This is a better and much more understandable presentation of the subject than any professor I ever had. Nice tie-in with electron spin and magnetism too. When I went through college I could work the math but never really understood what it represented. After watching this video it finally all makes sense..

THANK YOU... SIR...!!! You have done a great teaching...to connect all the basics we know about this PRAPANCHAM... and took us far beyond...!!! IT IS FUN AND WISDOM...!!! ENJOYED VERY WELL...!!! THANKS AGAIN...!!!

I like how you invited energy to the party. That’s the thing that always make magnets seem like magic things with endless energy.

This guy is amazing. I've learned so much from him over the years. Thank you, Math and Science.

I've been waiting for this! Hoping for more lessons about electromagnetism

Great lesson. Good blend of theory and practical. Please make more videos like this.

Very well done! As you mentioned, we truly don’t know what’s happening at the quantum level, but models help our feeble minds to come up with calculations to describe our universe. I believe that magnetic field lines do not exist. The magnetic field is continuous throughout, dissipating as it extends outward. In other words, with the iron filings, one would believe that in between the lines, there is no field. When actually, each iron filing has become a magnet repelling another iron filing in its next concentric circle. Also, when looking at an electron’s magnetic field, you can use the left hand rule to show the direction of the magnetic field. Again, great discussion Jason of this complicated topic. 👍

So clear explanations. As an EE it is like music to my ears. It refreshes the concepts in a limpid way Thank you and God bless!

Excellent presentation. I think it is worth considering at 1:7:04 that, as your arrows show, the external field of the solenoid does not cancel but the additive effect is diminished by the reducing flux density, and thus tends to zero in the ideal solenoid. If the external field did cancel every case would behave as ideal.

Magnets and magnetic fields are such fascinating topics! It's great to see content exploring how magnets interact with the world around us. The way magnets can attract or repel each other and how they influence objects without physical contact is really intriguing. Plus, the concept of magnetic fields extends to so many areas, from compass navigation to data storage in computers. It's amazing to think about the invisible forces at play!

This is better than my physics w/ calculus 2 class and its free! Thank you sir

I've been fascinated by magnetism lately. Because it already is an invisible force that can easily explain why the Earth's magnetism could be the source that's turning the constellations through an invisible axis that makes a vortex which creates our gravity. Especially when you see how quantum locking works. It's just fascinating stuff.

Cool dude! This is the Science teacher everyone needs! ☺️👌

One of the best science videos so far. I know it's not easy to create this kind of video and the time. Thanks so much sir.

You sir, are absolutely brilliant. Thank you. I'm an electrical engineer, this is by far the best lesson I've ever come across. 👏👏👏

I am a Porter but I love science talk , I allow myself to give students an advice to review what Richard Feynman said in this part from 1:40:28 to 1:41:20.

Excellent explanation! when I was a student I had to read so many bookss and cost me a lot of time to have a real picture of the physical phenomena. Now Jason, in less than an hour, explains everything so clearly!!

This is real magic🎉❤

I really like the way you explain these concepts. I can just see Michael faraday doing the same things amazing children. They didn't need the math, but the evidence is locked into their minds when they get in the physic of electricty. Thank you, I enjoyed it.

Excellent. More importantly, those that want so badly to have firm, definitive answers for every baseline why...why? Show me a universe where all the minutia is known and I'll show you a place where it would be miserable to live. The thing that is important/relevant for us is pragmatism. We observe the tendencies of how the universe gets on with its business and we embrace that as our way forward. Science doesn't need absolute, fully sussed out truths to go about its business. In fact, science expressly works only under a rubric of tentative truths. That's unknown by and/or lost on many.

Amazing video sir. Thank you for illustrating everything so clearly. I'm very interested in the theoretical physics of Electro Gravitics and Over Unity energy machines. I'd love to see you do work on those things.

This is a very good demonstration of how magnetic lines couple together to form closed loops of a magnetic field in the air or in space. Once the lines are formed/coupled together and everything stabilizes, the lines are coupled together without moving from pole to pole actually. And that is why we saw steel filings being coupled and attracted to both poles simultaneously. You did a very nice good of explaining why the fields are generated within each atomic structure and magnetic domain. The angular rotation of each atom's electrons is random, until the magnetic field is introduced to see its region of magnetic influence. Thank you for helping young people increase their knowledge of physics. QED

I think you explaned it very well but I am even more satisfyed with that you admitted that it is probably just the functioning of it you explaned and not the total truth. I am especially happy with that you explaned magnetic attraction in a way that is actually a pushing effect. It is just like that vaccuum doesn't suck. It is the air aroud that pushes things into the vacuum.

Great class for anyone interested in electricity such as myself!

It's so well explained that I understood every single aspects. Thank you so much. I love it. Subscribed.

How Do Magnets and Magnetic Fields Work? Good question. I like this video because it provides a lot of knowledge. Always success "Math....."....Pekalongan, Central Java, Indonesia On

At 24:26 --- that looks strangely familiar to a black hole. What if a black hole is just a super dense sphere of a matter but this matter is a made of a material that we don't know exists yet, the material cannot be seen with the naked eye but it's there, it's invisible but it's there, we just can't see it. This material is so incredibly dense that it generates an astonishing crushing gravity that affects things from thousands of light years away. This sphere is also spinning incredibly fast. So when we look at it, we see what we see at 24:26 matter being pulled towards a center with absolutely nothing in the middle, just an empty space. They say that black holes have solar masses, so that means the black hole it's not just a black hole but a sphere of matter being crushed down to the sub-atomtic level but because gravity is so strong the electrons and matter are creating something that we cannot understand, something that the intense gravity is holding together. If the black hole grows as it consumes matter, then there is no singularity, this means matter is falling towards the center and is collecting somewhere causing the gravity to grow and grow. This is a frightening thing to think about because the more matter collects the more intense the gravity becomes, the black hole would get so big that gravity would reach an astonishing force that will eventually explode as the core cracks under pressure, releasing so much energy that another universe is born from within it ... that sound familiar too?

Thank you. Watched your video several times. Would have been good to have it when I was slogging through engineering physics. I and my fellow students were buried in calculus, not having physical models for the phenomena we studied. Thanks.

Thank You again Sir, if there are small particles, I'll call them magtiles (magnetic-particle) making up magnetic fields, then electrifying a bar magnet for example, 1st would bring all of the electrons to a higher valence shell, but if it is emitting mag-particles, it should increase those, creating a larger field. The more power, wattage, the stronger the field, until we, it could repel, lasers, masers, bullets, whatev? But more than that, Iron, Fe for example, is much lighter, stronger, workable, less brittle than Lead, Pb, space radiation, or electrical shielding, for deeper space travelling, space craft skin, or electronic component shielding. Now a magnet, next to a coil, or inductor, might be able to induce a current +/- into the base, or gate of a transistor, both stronger, and faster, with less heat, or friction, parts that last longer? Yay Yay or Nay Nay

Whenever you're handling neodymium magnets take care never to let them slam together because they will break easily. they're quite brittle. regular magnets probably could break as well but definitely neodymium because they're a bit stronger and they will probably slam together a lot harder

The most honest scientific explanation

Excellent explanation of magnetism and the idea of mathematical models that may or may not fully explain what really goes on. Very enlightening. A huge thanks.

Excellent lesson. I was planning to make speakers and before that I wanted to learn magnets thoroughly and I am so glad that I found this video. Keep up the good work

Great demonstrations and explanations! Really appreciate your time and efforts. Thank you.

Now get the most expensive rare earth magnets, bolt opposing sides together, weigh them and find an equal weight. now drop them from a few stories and see which one lands first. Love the channel btw cheers 🥂☺️

How can I appreciate your teaching other than appreciation

Thank you so much for this you’re a great teacher.

You're so amazing teacher everyone would love that just the way you described it incredible teacher!!!

At 15:42, The North Pole of the compass is pointing to the south of the magnet. So why don’t we correct it, that North pole of a compass points to the south magnetic pole we’ve been mistakenly calling North Pole. Our bad

The last 10 minutes really explained the attractive and repulsive properties of magnets. Keep up the great work!!!!

Excellent Sir!! Im sorry to only hear this at 77 yrs of age!! Pse continue!!

Great lesson! I would love to see your Iron fillings experiment on repelling and attracting magnets. Am I correct in assuming 2 opposite magnets when attracted together form one larger magnet?

i've come to understand it better learning about qubits and quantum operators... at each point in space, we have a field of operators that affect the wave function of a object... if you have an object at point A with initial conditions X: the velocity operator will define its motion the electromagnetic operator will define the behaviours of electric charge the gravity operator will define it's path through timespace when you look at an object, you are applying a 'positional' operator on the object's waveform to find out where it is... applying the operator collapses the wave form... the conditions of operation are inherent in the fields not the object...it only has finite initial conditions regardless of field encountered...

A two hour video titled "How do Magnets & Magnetic Fields Work?" at around 11:20 "I'm not going to tell you how magnets work"

The antecedent to a directional vector is motion, the earth is in constant motion, which is why we have weight, a density layering and gradient When objects are released from a height they aren’t accelerating, in fact they’re decelerating until they reach terminal velocity then there’s no motion, so nothing is falling When a bottle of water and air are released from a height there’s no displacement which means there’s no acceleration Gravity is just motion

Thank you so much for this video! I really feel like I have a better understanding of magnetism, and you have inspired me to do further research!

Violent Jay sent me here.

Very satisfying video, thank you dear. We hope to see more videos like this one.

Briliant lecture.

you my man--are great---ty -i,m 77 and do wish i had you as a teacher all the way through--you are very understandable--thanks again

Another Excellent lesson , Jason.

you are a genius! you live science and have the power to magnetize with you anybody that hears your videos, they are so profound and thorough!! thank you very much!!!

According to your experiment, Current generates Electromagnetic effect. Which means that in ferro magnets, there is flowing current enabled by the interraction of the electrons in the combining atoms. So magnetism is simply the flow of current.

Perfect explanation, interesting and clear. Thanks a lot!

A very interesting and useful lecture. Thank you very much.

awesome... you've ignited my curiosity in science... As you explained the rotation of electrons, my thoughts go to whole big picture of why matter rotates around the centre points gravitational objects in the universe...

The best teacher!

we'll delve into flux density, which describes the strength of the magnetic field in a specific area.

I’d like to know the brand of your microphone. Good quality there.

Great explanation...Enjoyed It..A Refresher For Me...

Thank you for very good demonstrative experiments and explanation of behaviour of magnets.

Nice lessons and more helpful and deep in content

Bravo.... Thanks for the very informative lesson. Science is awesome, even more so when its easily learned. Well done...

From 1:17:40 to 1:26:35 is a talk about how magnetic fields exist due to their interaction with electrons (which are components of atoms). Does this mean that if I took two bar magnets into intergalactic space, their magnetic attraction or repulsion would be greatly reduced because the number of atoms, and consequently electrons per cm^3 is greatly reduced?

Excellent Sir, lots of respect and love for you,

Excellent! Can you do this?: Put a normal bar magnet (straight line) down vertically, then bring a piece of non-magnetic steel or whatever next to the North Pole. Have it lay on the page also. Once in the same line as the first magnet, once at a 90 degree angle where the first magnet bisects the second, and once where the first magnet attaches to the end of the second (but still with the second at a 90 degree angle). And do the paper plus iron filing thing on top at each of the three configurations.

THANK YOU SO MUCH!!!! It was really awesome, I've learned a lot! btw love these 10-minute format videos 😋

The best video I never seen before, thank you for sharing

Whoa, the intro has me hooked!

wonderful. recommend it to everyone.

That was an awesome explanation 👍👍 thank you for taking your time to explain a difficult question about how magnets/magnetism work .

Hello, I wonder if you consider an electric charge in the first place as being the main source of work for a permanent magnet ? A very basic permanent magnet consist in an alloy of 3 elements: iron, copper and nickel let’s say and each element plays a role in recirculating the electric charge in a permanent magnet: iron will absorb all possible charge, copper will offer a fast path to circulate and nickel with high resistance will retain the charge inside the alloy. Any permanent magnet is a self resonant device which requires only 1 charge at a time while providing continuous work for extremely long time. A permanent magnet is based on its ability to retain an electric charge which is placed when the alloy is brought to a certain temperature which allows an alignment of its atomic structure in such way to not permit electric charge to leave. So, we can fracture any permanent magnet down to its single crystalline structure and every single particule containing iron, copper, nickel will display magnetic field as long as they are able to retain the electric charge. Based on working frequency and most common permanent magnet contain ferromagnetic element (iron) and will be self resonant for a frequency at which ferromagnetic can resonate. As such, based on frequency we can have an electret which is self resonant at a higher frequency according to main element used to retain electric charge (electric charge placed under heat treatment as “normal” permanent magnet). In this case we can observe that “small” electric charge is available to be extracted as a surplus of the initial charge due to high frequency at which resonate and available power can be calculated in watts/pulse … obvious the power is multiplied by the time constant for oscillations. The difference between permanent magnet and electro magnet consist in 3 elements for permanent and 2 elements for coils (electromagnet) which in turn offer the alternative to be switched off as and when required for an electromagnet in a controlled dampened self resonance. But, coils can be made self resonant and act exact like a permanent magnet and Nicola Tesla have patented his invention for bifilar coils for electromagnets where resistive and capacitive impedance cancel each other and extra energy is made available for further use and I mean “extra” energy which is not required to maintain self oscillations for an RLC circuit. I think this is how should be explained magnetism and electricity with all the benefits that we can observe. Magnetic field is a consequence of electric field. Magnetic field does not exist without electric field and viceversa ! When explaining “south” and “north” of a permanent magnet we MUST consider the electric charge placed in an alloy in the first place and observe electric flux for most positive to less positive (or negative if you prefer) … by analogy with an electromagnet ! Also, please update information about how magnetic field is represented as it will always follow the spiral motion of a charge … all the oscilloscopes shows the “wrong” movement as they are only able to display 2 dimensions … would they be 3 dimensions we can see the spiral motion and better understanding of “magnetism” can be achieved.

Thank you very much. Amazing presentation.

amazing visual presentations. super fun!

TQ SO MUCH SIR, FOR DETAILED INFORMATION OF BASICS

Thank you very much for your great information about the magnetic field n magnets. You are a great teacher to explain things easy n simple way.

Thank you for this helpful lesson.

Thank you, very enlightening!

You Sir, are not a good teacher. You are a superior teacher ♠️

Excellent explanation. Your way of explaining is very good.

what an excellent lecture, thank you

most excellent presentation of this topic. subbed. 20:37 right on

Super explanation. Thanks

yeah "mesmerizing" ist most certainly the word! Terrific doing, Mr. Jason! :) cheers!

i wish i had you as my science teacher! great video. thanks.

@41:30 attracted/repelled that's the system using in door bell, when you push the button it send a current in the magnet which will be attracted to the cloche and released and again ...

Fantastic work. Amazing. Thanks so much.

Explained very well.
