When pp side of shiny rock face vagina side of shiny rock they connect. When pp side of shiny rock get near pp side of other shiny rock they repel because that is gay.

basically we don't know. in its quantum mechanical form, it was discovered by posturing that particles can have phase invariance between observers and for that to be the case there needs to be the electromagnetic force to make the universe self consistent

Infinity is zero (sometimes).
Infinity can be approached, but never reached.
Zero can be approached, but never reached.
Magnets are pulling to a singularity.
What remains after zero and before Infinity, is actuality, an arising order, from addition and subtraction.
And what drives (all of) actuality cannot be known.

particles have charges and opposite charges attract

>>15429569
particles dont real
they are imaginary constructs

>>15428923
>But despite appearances, electrons don't spin
This is something that physics and chemistry teachers that don't really understand quantum mechanics teach because they were taught it when they were students. The spin of the electron is angular momentum and it can be converted to other forms of angular momentum which are unequivocally related to spinning.

This question always has two parts that no one ever bothers to distinguish:
>why do magnets attract?
This can be explained with classical electromagnetism
>why do ferromagnetic materials exist?
This involves quantum mechanics

>>15429753
>This can be explained with classical electromagnetism
Now what is electromagnetism

>>15429760
Spin orbit coupling

>>15429693
Spin is like angular momentum (it's components commute like angular momentum) however, spin is intrinsic to the particle: i.e. all electrons have spin 1/2

>>15430087
It is angular momentum, period.

Ice is slippery, everybody knows it, no problem.
[...] Thats kinda curious, ice is extremelly slippery. It's very interesting.

The earth itself is like a giant magnet. Earth's molten core generates a magnetic field.

Nice sesquipedalian garbage.

Electrons don't spin.
But they have angular momentum.
Is equal to saying:
Electrons don't spin but they rotate.
It is absolutely retarded meme Magic.

How in the fuck can anyone know that a particle has any properties such as spin, when it cannot be observed or isolated because it only exists in a cloud of "probability".
Theoretical physics is as retarded as a married Bachelor and actually should be called hypothetical physics.

>>15430464

This is not a proof.
Dude, the spin or angular momentum of electrons does not even make sense when they only exist in a cloud of probability.
A spin is arround a axis.
This would also imply that a electron has a constant up or down.

Picrel is the retarded illustration of spin releating the the magnetic field of single elctrons.

This is 2D.
This inplies electrons have a parallel axis to each other.
Otherwise they could just flip and lean and then the direction of of the "spin" will change.
Please provide the specific experiment, which demonstrated the spin or rotation of an electron arround it's axis.
I don't understand how one can just believe in the claim of spin while also believing that electrons exist in a cloud of probability and unpredictably apeear here and there arround the nucleus of a atom.

>>15431163
>This is not a proof.
It is as close to a proof as you are going to get outside of mathematics.

Just because you don't understand something or because someone made a bad illustration doesn't mean everyone is doing it wrong. Grow up.

In reference to your actual objection the spin axis can change with time, and if you put a spin 1/2 particle with the spin axis misaligned compared to some background magnetic field it will precess just like in classical physics. (If any slightly less ignorant reader has doubts about my use of "spin axis" I am talking about the Bloch sphere)

>>15427968
Some wierd shit with photons, doesn't make any sense

>>15430464
Electrons have orbital momentum but no internal spin

Memematics.

>if you put a spin 1/2 particle with the spin axis misaligned compared to some background magnetic field it will precess just like in classical physics

Proof?
Can you provide an experiment in which they show this?

It appears like they don't have one proof.
So they try to explain a esotheric claim with maths.
But even then it does not make sense, so they have to add a lie to a lie to fill the inconsistentcy gap.
And again of course it's again not provable but with maths and ""thought experiments"".

>>15431221
Proof?

>>15427968
Quite literally, they don't
[math] \vec{F}=q\vec{v}\times\vec{B}[/math]
[math] W=\int\vec{F} d\cdot\vec{r} [/math]

>>15431225
They move around the nucleus therefore they have orbital momentum but their internal momentum is zero because their radius is ~0.

>>15431232
Please provide a proof that electrons were observed in orbitals

>>15431263
It's self evident:
1)Electrons and protons actract each other
2)We know electrons and protons exist in the atom
3)Therefore somethimg it's stopping them from falling into each other, and that is orbital momentum.
