WebJun 9, 2024 · If two similar-looking parts are made of different materials, they will also have different permeability and retentivity. Permeability affects how easily magnetic current travels through a part and how it is attracted to small flux leakages due to the flaws. The retentivity of a material affects how well the material holds its magnetic field.

WebSep 24, 2024 · Retentivity noun (sciences) the capacity to retain magnetism after the magnetizing action Coercivity Coercivity, also called the magnetic coercivity, coercive … WebSoft magnets are also ferromagnetic materials which can retain their magnetization as long as the external magnetic field exits, i.e. they have low retentivity. They also have a low degree of coercivity, i.e. their retained magnetization (although being very less) can be eliminated very easily. Hence, they can be easily magnetized and demagnetized. WebRetentivity (R): It is a measure of the remaining magnetization when the driving field (H) is dropped to zero. A permanent magnet should have high retentivity so that the magnet is strong. Coercivity (C): It is a measure of the reverse field needed to drive the magnetization into zero after being saturated. tarik minty
