Firstly, there are three utility parameters to determine the function of the powerful NdFeB magnet:
Remanence Br: When the permanent magnet is magnetized to fullness and the external magnetic field is removed, the retained Br is called residual magnetic induction.
Coercive force Hc: Reduces the magnetization to the zero of the fully magnetized permanent magnet, and the required reverse magnetic field strength is called magnetic coercivity.
Coercivity
The magnetic energy product BH: represents the magnetic energy density established by the strong neodymium iron boron magnet in the air gap space (the two magnetic pole spaces of the strong neodymium iron boron magnet), that is, the air gap unit volume.
Magnetostatic energy. Since this energy is equal to the product of Bm and Hm of a powerful neodymium iron boron magnet, it is called a magnetic energy product.
Magnetic field: the magnetic field of the magnetic pole is the magnetic field
Appearance magnetic field: The magnetic induction intensity of a specified orientation of a permanent magnet external surface.
