Neodymium is a paramagnetic material, so how do we have a permanent neodymium magnet?
Neodymium magnets are not made from pure neodymium; instead, they are ferromagnetic alloys that include neodymium, which allows them to exhibit permanent magnetism. While pure neodymium is paramagnetic, the alloying process with other elements such as iron and boron transforms its magnetic properties. This discussion also highlights the differences in magnetic attraction between regular steel and stainless steel, as well as the magnetic properties of nickel compared to nickel coins.
