๐Ÿงต Can magnetism be observed?

Anonymous No. 16284971

By looking at the material structure of say a ferromagnet?
Can you actually see those alleged domains responsible for magnetism in the crystal structure?

Yes. This is what inelastic neutron scattering does. Neutron scattering gives structural information about a crystal, like x-ray diffraction, but neutrons have spin. Inelastic neutron scattering measures the kinetic energy change of a scattered neutron due to its interaction with the magnon of a magnetically ordered crystal. You get energy as a function of structure factor. This gives you structural information about the magnetic ordering of the crystal.

Not entirely simple to understand, but what did you expect?

You can also get such information from hitting a magnetically ordered crystal with other types of spin particles. For example, people have also characterized magnetic ordering at the microscopic level by muon spin resonance:

>Energy transfer as a function of structure factor

Btw, the picture with Greta Thunberg would be more informative if it was normalized to per capita emissions and the starting point at the year 2000 shown. That's a pretty selective presentation of data

Yes, look up "magnetic bubbles"

Global warming affects everybody. If any nation doesn't do their part, then no nation should bother.

That's not a very useful point of view. I hope you guys take that line of thinking to its natural conclusion and refuse to vote

Voting is completely different because it is like flipping a coin. Not everybody is going to win the lottery, but someone will.
It's high time China and India pay for their climate crimes.

I don't know if it's on the right scale, but there are thin sheets out there that let you view magnetic fields

global warming doesn't exist, its a fairy tale. if global warming were real sea level would be rising and it isn't, which proves that global warming is fake

its pretty much a fact the china shills the global warming meme as a means of weakening their enemies in the west. chinks know all about abusing the bougie baizuo cuck stereotype, its a part of their culture. "savior" is an insult in modern chinese

The curl of an electric field will produce a changing magnetic field. Likewise since electrons in atoms have an electric field due to their charge and have a type of "angular momentum" called spin they "curl" their electric field by rotating and thus produce a magnetic field, this compounds atom by atom until you get stationary magnetic field producers like fridge magnets.

Africa's carbon emissions are greater than Europe's
How come nobody cares about this?

that's the theory yes. but how do you observe it?

Anonymous No. 16292159

All the answers here are true, but keep in mind that there are also things influencing magnetism that are too small to see using visible light microscopes as well, so the answer is multifaceted.

I'm disappointed that I'll probably never live to see Earth with over 1000ppm CO2 and nature thriving at it's maximum potential.
