Peridotite, a coarse-grained, dark-coloured, heavy, intrusive igneous rock that contains at least 10 percent olivine, other iron- and magnesia-rich minerals (generally pyroxenes), and not more than 10 percent feldspar. It occurs in four main geologic environments: (1
Iron is a mineral that is found in a range of foods. It helps to transport oxygen around the body, making it essential for life! It is also important for producing energy, optimal immune function, and storing oxygen in our muscles (this is what gives muscles their red
However, iron has a relative permeability of 5,000 when it is 99.8 percent pure, and the relative permeability of soft iron with 99.95 percent purity is a massive 200,000. This huge relative permeability is why iron is the best core for an electromagnet.

Pure iron is remarkable in its complexity, not only because of its many allotropic forms. There are hidden features related to magnetism which, for example, make the expansion coefficient of austenite greater than that of the more loosely packed ferrite – one consequence of this is that austenitic steels deteriorate when subjected to a coination of stress and thermal fluctuations.
