I’m too stupid to understand what that article is talking about. Can someone translate to layman’s terms?
I could be wrong but as I understand it. You know magnetism based on positive and negative poles, now they can read and write SPIN, which is another property of electrons (that are in everything, even things nonmagnetic). If it’s true, and scales, we could use non-ferrous better materials to achieve what we do currently with ferrous materials.
Sooo we can magnetize nonmagnetic materials?
Tractor beam when?
chatgpt can eli5 summarize. who knows if its accurate enough
What value is a summary when you fully acknowledge that you can not trust it for accuracy?
ChatGPT cam bullshit about anything, but odds are anything complex will be wrong.
Even simple things are probably wrong.
I would not even trust it to summarize nuanced details in a lengthy article, let alone something science related (especially about new discoveries).
There was a second?
I have no idea about the numbering, but I know of at least
- Ferromagnetism (like a fridge magnet)
- Antiferromagnetism (opposite of ferromagnetism at an atomic level)
- Diamagnetism (makes superconductors float)
- Paramagnetism (like that spinny frog)
These all indicate how a material reacts to a magnetic field. This article discusses “altermagnetism”, which is somewhere between ferromagnetism and antiferromagnetism.
Yeah, Paramagnetism.
Is that the kind that jumps out of aeroplanes?
Nah, it’s the one with the chair
This thread is already too smart for me
Pretty sure it’s the other non-brand name for acetaminophen.
That’s the copper one right?
No, the aluminum one.
That’s the copper one right?
Fucking magnets, how do they work?
Unironically, magnetism is similar to charge, which is similar to mass.
You (probably) wouldn’t ask “But why does an atom weigh anything?” or “why do opposite charges attract?” All these things are just intrinsic properties of matter: they just have them.
So the answer to questions regarding why anything has mass/charge/magnetic moment really come down to “they just do.”
Now, if you want to talk about how and why magnets work at a macroscopic scale, we can have a long and interesting chat about long range ordering and phase transitions, but I’ll leave that for now :)
There’s a lot more to it than “they just do” we just don’t know yet because there’s actually a lot we don’t understand about the fundamental properties of, well, fundamental particles.
See the higgs boson as for why matter has mass. We used to say “inertia is a property of matter” but some clever fucks figured out why and then proved it.
Mass & gravity are still way easier to understand on a fundamental level, especially since everything has a certain amount of mass and thus affects and is affected by gravity. It’s a much simpler concept. (“Natural”) magnetism is (so far) very material specific and I don’t think I’ve seen a good explanation as to why exactly. Magnets certainly behave very differently than other materials and that causes this mysticism in people when they think about magnets. Given the still ongoing research into magnetism and related things like superconductivity there’s certainly a lot still to learn.
This reminded me of Richard Feynman talking about this very topic. Always enjoy rewatching it. https://youtu.be/MO0r930Sn_8
It’s funny because the actual physics explanation is “they just do”.
It’s the craziest part of quantum physics. “Why is this stuff having the observed behavior?”
Based on all evidence and theory, the answer is that it quite literally just does.
Worth a read, I feel like I read some hard sci-fi.
