Ferromagnetic Metals (Extended Version)
Only a few metals can be magnetized. These are called ferromagnetic metals and include iron (from ferrium in Latin), nickel, cobalt and alloys of these metals with samarium and neodymium for very strong rare-earth magnets.
Above a temperature called the Curie point, the magnetic properties of ferromagnetic metals disappear. Instead, atomic dipoles are aligned in regions called domains.
