Iron is a grey, silvery metal. It is magnetic, though different allotropes of iron have different magnetic qualities. Iron is easily found, mined and smelted, which is why it is so useful. Pure iron is soft and very malleable. Chemical properties. Iron is reactive.

What makes iron a magnetic material is that it has unpaired electrons, however that isn’t quite the whole story. Having unpaired electrons is necessary for ferromagnetism, but not sufficient.

Why is iron magnetic? The long‐sought explanation of the origin of ferromagnetism, which involves interactions both among the bound electrons and between bound and itinerant electrons, will guide the search for new magnetic alloys. Yes, iron is a magnetic material. It is an element by itself by alloys containing iron would also exhibit varying degrees of magnetism. The other magnetic elements include cobalt and nickel. Iron(II) chloride is used as a reducing flocculating agent, in the formation of iron complexes and magnetic iron oxides, and as a reducing agent in organic synthesis.

However, blood is not magnetic in a conventional sense. In other words, it is not ferromagnetic which is what most people understand as magnetism.

The unravelling of the origin of magnetism in iron, cobalt, nickel and their alloys has been a fascinating subject of study for many years. It is elusive because the structure of the valence electrons in the transition metals is very complex.

Stuart - The fact that blood contains iron is one of the reasons why some people believe magnetic bracelets might have an effect on the human body. However, blood is not magnetic in a conventional sense. In other words, it is not ferromagnetic which is what most people understand as magnetism. Yes, iron is a magnetic material.

Magnets attract iron due to the influence of their magnetic field upon the iron. Before a piece of iron enters the magnetic field of a magnet, the polarization of the iron s atoms is random.

The inductive sensors with selective performance can differ ferrous-magnetic metals (e.g. iron, steel) from non-ferrous-magnetic metals (aluminium, brass,

(7); In ancient times, people did not know how very abundant iron was on Earth. … Magnetic separator separates the iron ore feed material into two or more components. If the purpose is to produce a magnetic concentrated iron ore then the other component which is non-magnetic is the tailings. In some cases there can also be a possibility of separating the less magnetic third component which is called middlings. The two iron halves won't have strong forces. A magnet half and an iron half will have fairly strong forces which will not change sign if you turn one by 180°. Unfortunately this is a somewhat destructive test.
