  • Ferromagnetism: Why Is The Earth Core Magnetic?

    This makes the tiny magnets in iron become promoted to high-energy states, pointing in the opposite direction with respect to their neighbors. This means that they are less aligned than before, so their 'combined' magnetism reduces. This goes on if you continue to heat iron until a point is reached beyond which iron loses its ferromagnetic properties and ceases to be a ferromagnet. Iron ...

  • Iron and Steel Slag Statistics and Information

    Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and iron are formed. The physical characteristics ...

    Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets.In physics, several different types of magnetism are distinguished. Ferromagnetism (along with the similar effect ferrimagnetism) is the strongest type and is responsible for the common phenomenon of magnetism in magnets encountered in everyday life.

  • Why Does a Magnet Attract Iron? | Sciencing

    17.04.2018· Most people know that iron is attracted to magnets, while other metals like gold and silver are not. Yet few people can explain exactly why iron has this magical relationship with magnetism. To arrive at the answer, you need to get down to the atomic level and examine the magnetic nature of an atom's electrons. Electrons and Magnetism.
