Not All Iron Is Magnetic (Magnetic Elements)

3-7-2019· Iron isn't the only element that displays magnetism.Nickel, cobalt, gadolinium, terbium, and dysprosium are also ferromagnetic. As with iron, the magnetic properties of these elements depends on their crystal structure and whether the metal is below its Curie point. α-iron, cobalt, and nickel are ferromagnetic, while γ-iron, manganese, and chromium are antiferromagnetic.

Metal Profile: Iron Properties and Characteristics

Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores.   The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.
