Why do Magnets Attract & Repel?

In this video, we discuss the intriguing world of magnetism, exploring the fundamental principles behind why and how magnets attract and repel each other. Join us as we unravel the physics of magnetic fields, magnetic force, and the underlying mechanisms that govern their interactions.
Discover the concept of magnetic field lines and how they provide a visual representation of the magnetic field's direction and strength. We'll discuss the energy density of magnetic fields and their role in shaping magnetic interactions between objects.
Through clear explanations and visual demonstrations, we illustrate how magnetic poles interact based on their alignment and proximity, showcasing both attraction and repulsion phenomena. Explore the relationship between magnetic force and distance, and learn about the factors that influence the strength of magnetic interactions.
Whether you're a student studying physics or simply curious about the properties of magnets, this video offers a comprehensive exploration of magnetism. Gain insights into magnetic domains, magnetic materials, and the practical applications of magnetic fields in technology and everyday life.
Join us as we uncover the physics behind magnets, magnetic fields, and the intriguing forces that shape their behavior in our world.

Jason is up there as one of the best lecturers, not in one field but in multiple areas, in my opinion.

[@MathAndScience]

Many thanks!!

[@WHO_ACTUALLY_CARE]

When I needed you the most you always come back

[@MathAndScience]

Awww what a nice comment

[@WHO_ACTUALLY_CARE]

@@MathAndScience you're always welcome you help me the most anyways with all subjects

[@alemswazzu]

Great demonstration. Real big picture ideas (forest) are needed to pull you out sometimes from staring at the trees.

[@humbled9948]

Thank you.

5:57 The way I’ve always understood it to work is that there were essentially an infinite, but maybe finite, number of field lines from the North Pole to the most South Pole region nearest to it which is most often the other side of the magnet. As the strength of the opposing field lines converge it’s like lightning finding a leader through the path of least resistance. Lots of nuances to how the materials essentially auto-negotiate that at the atomic and quantum level and how they transmit the energy through the field and what is actually causing the force to be applied over the distance!

If talking about energy a video about what energy is and entropy is needed.

[@tresajessygeorge210]

THANK YOU... SIR...!!!

[@pk2712]

This is a very good explanation of how magnets work .

[@drumtwo4seven]

Excellent explanation 👍 Thank you for sharing this

[@landesnorm]

So enjoyable to listen to and think about.

[@MathAndScience]

Indeed!

[@HappyworkingTynsong]

The best explanation I ever had

[@Songfugel]

3:22 because at quantum field level all energy and matter are just quantum field wave excitations from 0 level, and all systems are trying to find the lowest energy level in each of these fields, the neutral flat state where the negative and positive wave excitations are both 0. The opposite charges atract each other, since they cancel each other either fully or partially, either way, reaching a lower and closer energy level. Opposites on the other hand repel each other, since if they come into contact with each other, they are trying to amplify the local energy deviation even further away from the flat 0 level

[@studytimebyfoziabarlas9890]

Great 💯

[@apollo-r5z]

If electrons emanating from the north pole of a magnet are considered to be in an up spin, and electrons from the south pole are in a down spin, then the counter rotating vortexes must attract one another, analogous perhaps to a Tesla turbines fluid flow. Whereas like poles having identical electron spins will repel.

[@Uk_me_adarsh]

Hell yes, I just reading about magnet and this doubt came, glad I found this popping in notifications 👍🏻, perfect timing

[@MathAndScience]

Perfect!

[@MathAndScience]

Perfect!

In college I asked my teacher why he didn't include electron domain theory with magnets . He shunned me said it didn't seem pertinent to magnetism. Now scientists say magnetic fields are photons !

[@spaceantelope1]

Virtual photons, they say. It’s utterly ridiculous. There is nothing emitting from a magnet. If you want to know what magnetism is and how it works, there is only one book, “Uncovering The Missing Secrets of Magnetism” written by Ken Wheeler. He has a KZbin Channel called Theoria Apophasis. He is perhaps the most brilliant man alive, and all his books are free downloads. He sells nothing, and has read everything lol! Thank me later

[@martinfarfsing5995]

@@spaceantelope1 I would venture to bet the new partical accelerators and atom smashers discovered the magnetism is made of photons . Prove me wrong Einstein.

[@SarrouTube]

The best was at the end… we try to make better models

[@DrDeuteron]

Don’t hate on virtual photons. In pop science they are wholly misunderstood. The don’t pop in and out of existence (that view ended in 1948) nor are they making a force like a thrown ball. When two charged particles interact, the EM field takes all possible quantum states, which are added coherently. This is they Feynman path integral , which cannot be calculated analytically. Instead, it is approximated by terms that are described by Feynman. Diagrams . The simplest of these shows the exchange of a single virtual photon. The diagram is not one throwing a photon and the other catching it. The diagram lives in momentum space , and the virtual photon has negative mass squared, a la a tachyon. It’s just a mathematical object. Nevertheless, it has polarization and other things the make it useful. For static situations, like two bound charges, you can use virtual photons to describe it…and it turns out to be the traditional Green’s function from the 1800s. Wikipedia has a nice description of it.

[@martinfarfsing5995]

​@@spaceantelope1thanks for stimulus to research magnetism from virtual photons . I never heard of that . Why are photons affected by gravity if they are non mass , gravity only acts on substance that have mass ?

[@magnitudematrix2653]

At 8:00. The reason why you see particles in wave functions is because of hydrogen or dye gas being compressed by charge differentials. Capacitance, reflectance and phase create space. Now breath in and you can feel the capacity of your lungs, hold your breath and you can feel the reflection of pressure in your lungs, breath out to phase the SPACE of your lungs.

[@AbacusincInfo]

Perfect timing-I am dropping a video about the Aurora and Solar flare due to the magnetosphere. I will link this in.

[@MathAndScience]

Cool, thanks

[@saftheartist6137]

Thank you!

[@mariocesarsousa]

Great explanation as always❤

[@MathAndScience]

Thank you! 😃

[@dalwinderssi4094]

Why magnet attract and repells at first place? Why alluminium is not attracted,why bismuth is repelled? Where is storef potential energy gone,snd comes back incase of iron?

[@drumtwo4seven]

Nice 👍 Polarity ?

[@rationalism_communism]

I have a reason on why things go to lower energy states, because it requires less energy, you cant have everything the same it wouldn't be possible.

[@just_a_tajik]

Once we asked our teacher in physics, if everything has a magnetic field, why don't magnets pull or push other things beside metals ? He didn't answered!

[@ChineloGloria-n1w]

🙏 good evening ,great people who are simply wonderful please I need Triangles

[@satyajitsahoo4234]

how scientist discover new things

[@BayaniMagtanggol]

3:10 - this proves the theory that everything came from nothing. nothing really magical about it.

[@sampamnl.8964]

ขอบคุณมากๆครับกับสาระสื่อการสอนดีๆ

[@govcorpwatch]

Why do electrons spin? No one knows. LOL. Quantum spin is NOT physical spin. They are balls of fluctuating vibrating standing waves. Blackholes have the same qualities as particles. Have you considered that "quantum spin" is the "stable" ergosphere of a schwarzchild proton?
