Magnetic Extraction Of Iron

Magnet Experiments: Iron Filings and Neodymium Magnets ...
· Iron filings are, as their name suggests, filed pieces of iron that look like a metallic powder. Their properties are, in some aspects, similar to ferrofluid, because they form a significant pattern when interacting with a magnet. Magnetic fields are invisible, but the pattern that both substances form represents the lines of a magnetic field.

Iron Extraction by Blast Furnace Metallurgy
Iron, when extracted from iron ore such as haematite containing iron (III) oxide, Fe2O3, in a blast furnace is called iron extraction blast furnace metallurgy. In this reduction reaction, oxygen is removed from the iron (III) oxide to leave behind iron. Generally, the extraction of metals and their isolation are based on three major procedures.

If a magnetic field is applied for long enough, the domains in the iron will remain aligned even after the magnet is gone causing the iron to become magnetized creating a permanent magnet. There are also some other metals that exhibit this ferromagnetic property including nickel, cobalt, and gadolinium as well as certain alloys or mixtures of metals and can be made into permanent magnets.
