Alignment of weakly magnetic metals during solidification,
Although aluminum and copper are both weak magnetic materials (with very low magnetic susceptibilities), the magnetic alignment of θ-Al 2 Cu phase could be reached , , in a proper magnetic field. The [0 0 1] crystallographic direction could be aligned by a strong magnetic field of 12 T .Permeability (electromagnetism) - Wikipedia,Diamagnets are materials with a magnetic permeability less than µ 0 (a relative permeability less than 1). Consequently, diamagnetism is a form of magnetism that a substance exhibits only in the presence of an externally applied magnetic field. It is generally a quite weak effect in most materials, although superconductors exhibit a strong effect.Magnetic separation plant - frjig,Application: Magnetic separation is used to separate materials of different magnetism difference. It is widely used in separation of kinds of strong and weak magnetic material like magnetite, titanic magnetite, magnetite pyrite, also called pyrrhotite, ilmenite, martite, hematite, specularite, siderite, limonite, manganese ore of pyrolusite & psilomelane, and wolframite.
