MPP
MPP stands for Magnetic Power Profile, Chinese name "magnetic power distribution curve", the magnetic power curve shows the relationship between magnetic field strength and magnetization, which can provide information about the magnetization behavior, permeability and hysteresis loss of the material. It is a new generation of wireless charging technology standard developed by WPC based on Apple's Magsafe. Compared with BPP and EPP, the biggest feature of MPP is the addition of a magnet ring for positioning and alignment, which can be easily charged for alignment.
Magnetic power curve data is important for designing and analyzing applications for magnetic materials, such as inductors, transformers, motors, etc. The magnetic power curve is usually based on the magnetic field strength (H) as the transverse axis and the magnetic induction intensity (B) or magnetization (M) as the vertical axis. The change in magnetic induction intensity or magnetization at different magnetic field strengths can be calculated by experimental measurement or simulation. By analyzing the magnetic power curve, we can understand the magnetic properties, saturation magnetic induction intensity, hysteresis loss, and other characteristics of the material, so as to better understand and utilize the properties of magnetic materials.
