Bro not only doesn't understand magnets, he doesn't want to accept that there is an explanation. He just wants it to be a miracle. Also the combination of words "fuckin magnets" is funny.

"Magnetic charge" is nonsense. The fundamental unit of magnetism is the flux loop, which behaves like a flywheel storing momentum.
Fundamentally, magnetism is not a point. It's a vector, like velocity.

Point is, the question of what is the nature of [blank] is more a question on what is the theory describing it, and what does that theory say. Asking about magnetism becomes a question of what is E&M + SR becomes a question about what is QED becomes... string theory becomes... So, as Feynman mentioned, how far down do you need to go until you're satisfied of "what is [blank]?"

"The nucleus doesn’t simply "suck" electrons toward it; it creates a strong electric field that attracts electrons, but the electrons' quantum mechanical wavefunction prevents them from collapsing into the nucleus. The nucleus’s internal dynamics, driven by the strong force between quarks, create a stable structure for the atom, while the electron's wavefunction is influenced by the electromagnetic field of the nucleus, forming a stable orbital arrangement around it. This balance of forces is what keeps the electron in proximity to the nucleus."

I wondered If the opposite charged quarks in a proton churn and jostle in such a way that the vibration they make is like the vibration you make with your hand in a pool of water to make a ball out of arms reach come near.

The EM field is apparently a real actual actually real thing that is composed of no parts (photons are not its parts, photons are its aggravated ripples) that spans all volume and direction of the universe in which other matter is not.

Space is an ocean made of no atoms, no discretions, but such an ocean called em field. As a diver can swim under water and the water displaces, coalesces and curves around their body, and the diver can pick up a rock and toss it:
So to an asteroid and planet travel through the em medium.

It's just very hard to understand, how something (pretty big, a single item the size of the universe) can be so volumetricly large, so locally moveable, and yet have no parts:

I was trying to ask about field line reconnection, how a body can pass through without breaking section that was previously self touching, now a body in its midst, or does this imply every non EM body movement is stretching the Em field every direction it travels?

If the ocean was not made of atoms/parts, and a diver tried to walk on the ocean floor through it, how could we conceive, of them being able to move a partless substance out of its way, i geuss break field lines

curl E = -dB/dt

There is no source of magnetism but if you swirl electric sources around the magnetism changes (from zero).

>swirl
The nature of the em field, the possible nature of its partlessness, that photons are aspects of em field but em field is more than just photons.

How are we to conceive, of being in the presence of a volumetrically large partless something, and consider the ways with which we may use various types and networks of matter, to twist and turn and swirl em field?

Some goey liquids appear as if they are partless as lots of macro things do, and we can twist and turn them, we can twist and turn a middle section without disturbing sections more distant from the center, but is this not due to the mechanisms of the parts of composition?

Or is it a silly hangup parts or no parts, it is conceivable to twist in location A and swirl, and have location D E F G unaffected?

Or is part of the point; twisting location A, does effect D E F G and beyond as radiation?

Have you ever been in a pool and made an object come near you that was out of reach, by dragging your hands in the water towards you?

Now you get how magnets work. Nucleus and electrons are like dragging hands in EM field.

Non magnetic materials the hands are all dragging in all different directions.

In magnets, the magnetic moments are alligned, the direction of hand dragging allign and multiple, like those old big boats with all the paddles out holes in the side

Yes, imagine the pool you are in is soda and you have a cheeseburger in your hand, and you scoop the soda in front of you with the cheeseburger like a paddle towards you, and this makes a floating hotdog drift toward you
