Why do magnets not blow themselves apart from repeling themselves? Do magnets self-repel at all? Why?

[Anonymous No.6900823]

Why are you so retarded?

[Anonymous No.6900908]

Duh, magnets are made from opposite poles and those attract each other, not repel.

[Anonymous No.6901686]

science does not know how magnets work

The intermolecular forces between the metal atoms holding it together are stronger than the magnetic forces repealing each other

[Anonymous No.6901717]

WTF? Polarity has been traced down to what level now, it's something above molecular right, or is it molecular?

[Anonymous No.6901753]

you idiot, north and south ATTRACT

why would it repel itself?

[Anonymous No.6901756]

>>6901753

Well he does have a point in that the various portions of each end of the magnet are the same polarity are they not?

I liked the theory of applying something along the lines of faraday's law to electron spin and electron orbit using the bohr model. No idea how it extends to quantum physics.

see that red paint on N side of the magnet? It contains lead and a thin coat of lead stops magnetic flux from going back to S pole of the magnet. That's why if you scrape that shit off, the magnet doesn't work as well and doesn't self-distruct.

North is a direction not a segment. They're tendency to repel or attached is affected by their alignment not proximity.

In general example, it doesn't matter how close 2 magnets' poles are together, because it only matters if there's a south pole between them if they are going to attract or repel from each other. And, this generalization works down to the scale of single atoms and molecules acting as magnets within a magnet you could hold in your hand. But, we don't know why anything behaves this way.

I have a magnetic monopole among my various knick knacks
Lemme try to find it and time stamp

[Anonymous No.6902147]

These faggotts know nothing, 'magnetism' is now recognised as an external solar effector force rather than an inherent material property. If you look CLOSELY at the picture, vast quantities of ionised hyrdrogen (+ve & -ve) are 'blowing' into our planets poles every day. It is only this self-referencing system that PROTECTS us from solar wind that allowed life on the planet to start. Magnetism is a property of external imfluences, not a property of material, its 'ability to explode' is restricted by this factor.

I am study at Moskva inztitut of Biological sciense, we know aves fly and migrat using this, aves are not magnetik

[Anonymous No.6902298]

is it true that there are huge manufactures at the nord and south pole producing positiv and negativ magnets by using the natural magnetic field?

Start at ~15:00.

If you're interested in the mechanics behind the magnetic domains this may help you: http://www.nobelprize.org/nobel_prizes/physics/laureates/1977/vleck-lecture.pdf

If you want something more precise/detailed you'll need to get a book i guess. I can recommend "Ferromagnetic Materials: Structure and Properties" by McCurie. There are tons of other books about this stuff though.

Do fish also have the same sensors?

[Anonymous No.6906349]

what happens is the magnet DOES blow itself up at the quantum atomic level, leaving only an atom of north and an atom of south, but then they attract and find each other again within one planck second, so you don't notice it.

Magnetism doesn't exist

There's just the electric force and relativity

https://www.youtube.com/watch?v=1TKSfAkWWN0

also maybe the electric force is just gravity curled up through extra dimensions, so maybe that's not real either

>hurrrr

or how about we go with the proper and widely accepted nomenclature and call it electro-magnetism? no? the autism runs strong with this one.

It is just the electroweak force and the Higgs Mechanism

>HURRR DURRRR

[Anonymous No.6906613]

Think of it like this.

You have countless atoms which are composed of positive and negative charged particles. In a metal, the negative charged particles, i.e. valence electrons, freely move throughout the metal. When the metal is magnetized, the electrons are all forced to move in the same way. When the electrons move, they produce photons. These photons are the magnetic field.

This is my layman's understanding of it.

There are no magnetic monopoles. Every magnet no matter how small has both "south" and "north".

>Electrical force doesn't exist

Nope. The electric force is fundamental, because the electric change is fundamental

>There's just magnetism and relativity.

Nope. There is no such thing as a fundamental force of magnetism. All magnetism fundamentally has to come from electric charges and relativity. There is no other way to create it.

>how about we go with the proper and widely accepted nomenclature and call it electro-magnetism?

Because it is misleading. The term "electromagnetism" was developed when we thought electricity and magnetism were on equal footing. We now know they are not, but we kept the term anyway because of convention. However, all fundamental terminology since then has dropped the word "magnetic.
