WebThe default definition of magnetic remanence is the magnetization remaining in zero field after a large magnetic field is applied (enough to achieve saturation). The effect of a … 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. atmaram gawandeWebAug 12, 2024 · The amount of magnetizing force initially applied, and retentivity of the material will determine the amount of residual magnetism. By applying opposite magnetizing force, the flux density will reduce. Coercive force is the amount of opposite magnetizing force to reduce the flux density to zero. pistola hitman 47
