This desperately needs a chart representing the relative strength of different magnet materials so that we can see where this is on the spectrum.

Damn even magnets are autistic now. Wokeness has gone too far!!!!
The woke force in magnets has gone too far!

It's interesting, but even if it's reaching near rare earth strength, can it be produced at scale? A less powerful magnet is useful if it can be cheaper.
Thats the challenge with novel materials, but it seems like they have gotten somewhat better at bringing them to market lately. For instance, novel battery technology
True the battery tech is really coming along, going to be interesting to see what prices are like when I go to replace the 22kwh worth of batteries on my boat next year. The fight between cheaper tech, inflation, and tariffs is going to be a nail biter.
Wut. Batteries all still suck
I was thinking of, for example, Sodium-ion batteries… sorry if your batteries suck mine are pretty good!
Those batteries suck
What’s wrong with them? What kind of battery problems are you having?
My batteries need to be replaced in less than 100 years, and the process to recycle them causes environmental damage and negative health effects.
Batteries are bad. Always have been, always will be. The solution is to avoid batteries. We need electric trains and busses that are grid tied.
The best battery is a non electric battery. That means running solar and wind during the day and the "battery" is running hydroelectric at night.
I appreciate where you’re coming from—batteries require dangerous materials and chemicals and also have health and environmental impacts.
With that said, you are not describing batteries—battery means “energy storage” in this context. What would you suggest for that? Air pressure? Water + gravity?
What about for local or portable storage?
Agreed. I mean electrical batteries suck.
Unfortunately cars can't run on batteries that don't suck. Which is why we need transportation that's grid tied.
Yeah, I mean generally, fuck cars. It sounds like you’re basically saying “more public transit” which I support.
Nice to see something else coming to recent news from Washington than dumb-assery and racism.
Well let's see...it's made from minority people's teeth? You must mix it in widow's tears?
There's gotta be some racist shit attached to this. Maybe only small tribes kids can mine it? The processing machines consume 8 pph? Puppies per hour?
I love when people discover scientific solutions to war, but war always gets the most funding.
could significantly advance clean energy technologies and consumer electronics such as motors, robotics, MRI machines
Wouldn't MRI machines intentionally use electromagnets, so they can be controlled more precisely?
From that image it appears that this magnet is formed from a crystal of manganese, iron, cobalt, and nickel, which weirdly are all direct neighbors on the periodic table.
What's with that? Is this a crystal thing? Like are similarly sized atoms more stable in a lattice? I'm no chemist, but this strikes me as interesting, or at least weird
Like are similarly sized atoms more stable in a lattice?
Actually yes. That’s why you can’t arbitrarily add random elements into a crystal (well you can a little bit). If the geometries vary too greatly you introduce stresses into the lattice.
