Magnetic materials, commonly referred to as the magnetic material refers to a ferromagnetic material is old and uses a very wide range of functional materials speaker magnets, and magnetic materials as early as 3,000 years ago by people understanding and application, such as the ancient Chinese natural magnet as a compass. Modern magnetic materials has been widely used in our life, such as the permanent magnet material is used as the motor, is applied to the transformer core material, used as the magnetic-optical disc memory, a computer with a magnetic recording floppy disk and the like. Said bits of information on a large, magnetic materials and information technology, automation, mechatronics, defense, national economic aspects are closely related. The generally accepted that magnetic element is defined by excessive iron, cobalt, nickel and its alloys can be directly or indirectly magnetic substances. After pressing the magnetic magnetization demagnetization difficulty can be divided into soft and hard magnetic material. Easily removed after the magnetization of the magnetic substance called soft magnetic material, not easy to go to a magnetic substance called hard magnetic materials. In general, the soft magnetic remanence smaller mold magnet suppliers, larger hard magnetic remanence. Magnet in the application of wireless charging wireless charging principles: wireless charging technology is completely without the aid of wires, using magnets to charge the device technology. Shenzhen Machinery wireless charging technology magnet, from the wireless power transmission technology, the use of MRI in the air charger and charge transfer between devices, the coils and capacitors in the formation of a resonance between the charger and the device to achieve efficient power transmission technology.
