Magnetism and magnetic properties Magnetism is a property of matter and it occurs in different forms and degrees in various Earth materials that act as conductors and insulators. For example, at low temperatures, metallic systems exhibit either superconducting or magnetic order. The degree of magnetism of a substance is due to the intrinsic magnetic dipole moment of its electrons.

Silicon steel sheet, the English name is silicon lamination, it is a kind of ferrosilicon soft magnetic alloy with very low carbon content, and the silicon content is generally 0.5 to 4.5%. Adding silicon can increase the resistivity and maximum permeability of iron, reduce coercivity, core loss (iron loss) and magnetic aging.
Magnetization Curves. Any discussion of the magnetic properties of a material is likely to include the type of graph known as a magnetization or B-H curve.Various methods are used to produce B-H curves, including one which you can easily replicate.Figure MPA shows how the B-H curve varies according to the type of material within the field.

In the separation of lead and zinc ores, ferrosilicon is a foreign body and the use of galena as a heavy medium would seem indicated; yet ferrosilicon has largely replaced galena for this work. The reason for it is that ferrosilicon possesses good magnetic properties which can be used to recover it from fouled medium.
