In the magnetic hysteresis loop showing the magnetic characteristics of a material, the remanence is the value of the flux density remaining when the external field returns from a high value of saturation to 0. The remanence is also called the residual magnetization. The higher the remanence value, the higher the useable magnetic flux density. The units for remanence are the Tesla [T] for SI units and the gauss [G] for the CGS unit system. The remanence is expressed as Br. For an isotropic material, the remanence is about 50% to 75% of the saturation magnetization, but for rare earth sintered magnet material, the remanence is about 95% or more of the saturation magnetization. This is due to the alignment of the easy magnetization axis with the magnetization direction.
First, the definition of magnetic tile: magnetic tile talking about here is a permanent magnet in a permanent magnet motor is mainly used in the tile-shaped magnets.Second, the magnetic tile classification: magnetic tile depending on their raw materials are mainly three categories:1, ferrite magneti

The ferrite is made of iron oxide and other ingredients. Generally can be divided into permanent ferrite, soft ferrite and rotating ferrite three.Permanent magnet ferrite, also known as ferrite magnet, is what we usually see the black small magnet. Its composition of raw materials are mainly iron ox
