Y30BH Magnet Magnetic Properties

Y30BH is one of the magnetic performance grade of sintered ferrite magnet, when we see it is Y30BH we know it is ferrite magnet material, its magnetic performance is characterized by the parameters of remanent magnetism (Br), coercivity (Hc) and maximum energy product (BHmax), the magnitude of these parameters determines the strength and performance of the ferrite magnets, the following is the typical magnetic performance data of Y30BH ferrite magnets.

Y30BH Residual Magnetism (Br): 

Residual magnetism, often referred to as residual magnetic induction or magnetic susceptibility, indicates the strength of the magnetic field remaining in the magnet when it is removed from the external magnetic field after it has been fully magnetized. For Y30BH ferrite, Br is typically in the range of 3.9 to 4.2 kilogauss (kG) or 390 to 420 millitesla (mT).

Y30BH Grade Coercivity (Hc): 

Coercivity measures the resistance of a magnet to demagnetization. It is the strength of the reverse magnetic field that needs to be applied to reduce the magnetization to zero. For Y30BH ferrite magnets, Hc is typically in the range of 2.7 to 3.1 kiloamperes per meter (kA/m) or 3.4 to 3.9 kilo-oersteds (kOe).

Y30BH Maximum energy product (BHmax): 

The maximum energy product represents the maximum magnetic energy that can be stored in the magnet material. It is calculated by multiplying the remanent magnetization (Br) and the coercivity (Hc). For Y30BH ferrite, BHmax is typically between 3.4 and 4.0 Mega-Gauss Oersted (MGOe).

It should be noted that Y30BH ferrite magnets will vary slightly in these values depending on the magnet manufacturer, if you need a quote or offer please contact the website customer service, we cherish every inquiry.
