WebMolecular Theory of Magnetism Not all pieces of iron and steel are magnetic. They can be magnetised and demagnetised. In the unmagnetised state the iron molecules point in all directions. When the iron is magnetised the molecules line up. Intensity of magnetism can be varied. When iron attains its maximum magnetism it is said to be saturated. WebThe molecular field theory explains the existence of a ferromagnetic phase and the presence of spontaneous magnetization below the Curie temperature. The dependence of the magnetization on the external field is, however, more complex than the Curie–Weiss theory predicts. WebThe study of magnetic domains is called micromagnetics. Magnetic domains form in materials which have magnetic ordering; that is, their dipoles spontaneously align due to the exchange interaction. These are … smart design bonded grip shelf paper
