Iron with a carbon content less than 0.02% is referred to as wrought iron, while iron with a carbon content between 2.11% to 4.3% is called pig iron. Steel falls in between these two categories. The carbon content impacts the performance of iron. The higher the carbon content, the harder the iron will be, but it will also become more brittle.

Making a Ferromagnet: An unmagnetized piece of iron is placed between two magnets, heated, and then cooled, or simply tapped when cold. The iron becomes a permanent magnet with the poles aligned as shown: its south pole is adjacent to the north pole of the original magnet, and its north pole is adjacent to the south pole of the original magnet.
