Physicists have uncovered a hidden third form of magnetism that challenges more than 100 years of established physics. Called altermagnetism, the discovery could transform future computing and electronics while opening an entirely new frontier in quantum research.

Keep asking how and keep getting deeper into it and you hit a wall of “it’s a fundamental force”.

That's also how gravity works. Would you say "nobody know how gravity works"?

I'd argument we know more about magnetism, since it's not a fundamental force, it is part of the electromagnetic force / field, which is fundamental at normal energy levels. We also know what energy level is required to unify the electromagnetic force with the weak force to give the electroweak force / field, which is (last I checked) more than we know about gravity.

IIRC, the discovery of the Higgs proved that gravity does couple with other forces through the W and Z bosons, but my understanding that doesn't result in true unification at the energy levels we observed. But, I'm not a high-energy particle physicist, I just find the standard model fascinating.

    Gravity works because mass warps space into time, so following the linear time into the warp causes gravity. We know how gravity works. We don't know how (or at least I don't) know why exactly mass causes spacetime to warp.
