Perfect tl;dr.

But did they succeed?
Tl;dr — yes, but it’s early days

Can we put 'em on a fusion reactor?
Asking for 8billion friends, much needed.

Fusion reactors need massive superconducting magnets, not cheap permanent magnets.
This work is better for reducing the environmental impact of the quickly growing EV market. Mining for rare earth metals is pretty destructive.

Can you help me identify a chemical compound that would produce a maximal magnetic field without the need for expensive, hard to acquire rare earth elements.
There are several chemical compounds that can produce a magnetic field without the need for rare earth elements. Some examples include iron oxide (Fe3O4), nickel oxide (NiO), and cobalt oxide (CoO). These compounds are not as strong as compounds that contain rare earth elements, but they are still capable of producing a significant magnetic field. Additionally, they are more readily available and less expensive than rare earth compounds.

Can you write a poem about it?
Sure, here's a short poem about a magnetic field:
A force unseen, yet strong and true
It guides and pulls, and makes things move
From iron filings to compass needles
The magnetic field is full of possibilities
It surrounds us, in earth and space
A fundamental force with a hidden face
But with the right tools and a curious mind
We can unlock its secrets, and learn to find
The power of magnetism, it cannot be denied
It shapes our world, and serves as a guide
From motors to generators, it provides the spark
The magnetic field, a force to marvel and embark.
