WebIt has high retentivity High coercivity High saturation Applications of Magnetic Hysteresis Magnetic material having a wider hysteresis loop is used in devices like magnetic tape, hard disk, credit cards, audio recordings as its memory is not easily erased. 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.
Retentivity Definition & Meaning - Merriam-Webster
WebMagnetic particle testing is a non-destructive test method, which can be used to inspect a variety of ferromagnetic components and products. These include castings, forgings and weldments. The method is used across different industry sectors, especially when determining if a component is fit-for-service. Industries that use magnetic particle ... WebAug 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. rabbit\\u0027s zy
