ELI5: Why are neodymium magnets so strong when neodymium is not a magnetic element?
gpt
Magnetism comes from the poles of atoms oriented in the same direction. Traditional iron magnets are made of iron atoms, which loosely orient in a direction. However adding neodymium forces the iron into a fixed structure, with almost all the atoms are oriented more efficiently. So the new crystal structure amplifies the magnetism of iron as neodymium magnets are made out of  neodymium/iron/boron.
