Scientists can transform non-magnetic materials into magnetic ones by precisely controlling the number of electrons in layered structures like magic-angle graphene, where the electron density determines whether magnetic interactions emerge or disappear.

Making Non-Magnetic Materials Magnetic?! | Brian GeradotAdded:
So you basically turn non-magnetic materials into magnetic materials.
>> Materials themselves aren't magnetic, but the particles in the materials are magnetic. You've heard of magic angle graphine. Graphite is non-magnetic. Two layers of graphine. You have a special angle. And you change the number of electrons sitting in these sort of lray puddles to just the right number. You can turn something that's completely non-magnetic into something that's truly magnetic, which is kind of like magic.
Just by changing the number of electrons, you can turn on and off the interactions and and generate, you know, magnetism.
