Permanent magnets will be magnetizing prior to use for their intended application in most cases. Permanent magnet will be magnetized when apply a magnetic field via its orientation direction and then achieved technical saturation with the increased external magnetic field. Different kind of permanent magnetic material needs different magnetic field to fulfill technical saturation. Remanence…
Intrinsic magnetic properties of permanent magnet which including remanence Br, coercivity Hcb, intrinsic coercivity Hcj, and Max. Energy Products (BH)max, is mainly depending on its composition and microstructure, then nothing to do with shape and dimension. However, magnetic parameters which simultaneously affected by shape and dimension, including gauss value, magnetic flux or magnetic moment, are…
The initial and general knowledge of the permanent magnet in most people includes attractive or repulse force between the magnetic pole and the attractive force between magnetic field and ferromagnetic objects. Pull force also can be utilized as a comparative measurement method in some specified circumstances besides conventional surface gauss, magnetic flux, and magnetic moment.…
