Magnetic Moment The generation of the magnetic field can be divided into two aspects: one is based on the moving current (electromagnetic induction), and the other is based on the spin of the basic particles of matter. The first is the magnetic effect of current that we are more familiar with, which is the magnetic [...]
Magnetic induction B and magnetic polarization J Practice and theory have proved that when a ferromagnetic or ferrimagnetic substance is magnetized in a magnetic field, in addition to the magnetic field in the substance, because the magnetic moments of the atoms of the ferromagnetic substance turn to the direction of the external magnetic field, it [...]
Permanent magnets in Apple's magnetic wireless charger Since the iPhone 8 in 2017, Apple has added a wireless charging function to all iPhone models, which is similar to other mobile phone wireless charging methods. It starts charging when placed on a wireless charger. This wireless charging relies on the transmitter coil and Accepting the alignment [...]
Magnetization direction and orientation direction The magnetism of permanent magnets mainly comes from its crystal structure that is easily magnetized. It can obtain extremely high magnetism under the action of a strong external magnetic field, and its magnetism will not disappear after the external magnetic field disappears. Therefore, "magnetization" is NdFeB A key step for [...]
Orientation Anisotropic Injection Magnets, Injection Magnets Orientation Technology Injection Bonded Anisotropic NdFeB Magnet The common molding technics of anisotropic ndfeb magnet are injection molding and compression molding. Two major application samples of anisotropic ndfeb magnet are sensor magnet and expansion valve. Injection bonded ndfeb sensor magnets made by HDDR ndfeb powder are widely used for [...]
About Some Magnet Knowledge Permanent magnet material: The permanent magnet material is magnetized by an external magnetic field and does not disappear. It can provide a stable magnetic field to the external space. There are four common metrics for NdFeB permanent magnets: Remanence (Br) units are Tesla (T) and Gauss (Gs) 1Gs = 0.0001T A [...]
