Important three performance parameters are available to determine the performance of the magnet:
Remanence Br: When the permanent magnet is magnetized to the technical saturation and the external magnetic field is removed, the retained Br is called the residual magnetic induction.
Coercive force Hc: The B of the permanent magnet magnetized to the technical saturation is reduced to the magnetic field coercive force, which is called the coercive force.
The magnetic energy product BH: represents the magnetic energy density established by the magnet in the air gap space, that is, the magnetostatic energy per unit volume of the air gap.
Since this energy is equal to the product of the magnet's Bm and Hm, it is called the magnetic energy product. Magnetic field: The magnetic field that acts on the magnetic pole is the magnetic field. Appearance magnetic field: The magnetic induction intensity of a permanent magnet body at a specified position.
Magnet products are used in toys, jewelry craft gifts, handmade gift boxes, leather handbags invisible magnetic buttons, plastic hardware products, audio equipment, and other industries.
