Magnetic materials are widely used in electroacoustic, telecommunication, electric meter, electric motor, memory components, microwave components, etc.Magnetic tape or computer storage device for recording language, music, image information
Rare earth is one of the raw materials for magnetic materials, such as rare earth permanent magnetic materials.That means rare earths can be used as magnetic materials.
Rare earth permanent magnet material is a kind of magnetic material made by compacting and sintering rare earth metals (such as cobalt, iron, etc.) composed of a mixture of samarium and neodymium with transition metals (such as cobalt, iron, etc.) by powder metallurgy and magnetizing with magnetic field.
Magnetic material, generally referred to as magnetic material refers to ferromagnetic material, is an ancient and widely used functional material, and the magnetic material as early as 3000 years ago by people to understand and application, such as ancient China with natural magnet as a compass.Modern magnetic materials have been widely used in our life, such as permanent magnetic materials used as motors, core materials used in transformers, magneto-optical disks used as memory, magnetic recording floppy disks used in computers and so on.Big bit information, magnetic materials and information, automation, electromechanical integration, national defense, the national economy is closely related to all aspects.However, it is generally believed that magnetic materials refer to materials that can directly or indirectly produce magnetism by excessive elements such as iron, cobalt, nickel and their alloys.Magnetic materials can be divided into soft magnetic materials and hard magnetic materials according to the difficulty of demagnetization after magnetization.Magnetized easy to remove magnetic materials called soft magnetic materials, not easy to remove magnetic materials called hard magnetic materials.In general, the remanence of soft magnetic materials is small and that of hard magnetic materials is large.
