Susceptibility and retentivity
WebSep 9, 2024 · Retentivity: The property of the magnetic material to retain magnetism even in the absence of the magnetizing field is known as retentivity or remanence. Coercivity: The magnetizing field (H) needed to demagnetize the magnetic material completely is known as its coercivity. What is the permeability of soft iron? WebThe basic difference between crystalline (standard magnetic material) and glassy metals is in their atomic structures. Crystalline metals are composed of regular, three-dimensional arrays of atoms which exhibit long-range order. Metallic glasses do not have long-range structural order.

It is only necessary to wind a few turns of wire closely around a specimen and to measure the emf developed across the coil terminals as an external field B 0 is changed with time, see Figure (6.2.7). The emf across the coil … Webmagnetic susceptibility, quantitative measure of the extent to which a material may be magnetized in relation to a given applied magnetic field.

WebKey (1) Retentivity is defined as the intensity of magnetisation remaining in the substance when the magnetizing field has been reduced to zero. Hence key (1) is not correct. Key(2) Magnetic susceptibility is the ratio of magnetic moment to unit volume but it is not energy dissipation (loss) in cycle hence key(2) is not correct. WebThe international symbol for susceptibility of the ordinary ('volumetric') kind is simply χ without any subscript. ISO suggests χ m to distinguish magnetic susceptibility from electric susceptibility but this may risk confusion with mass or molar susceptibility. Some writers have used χ v to indicate volumetric susceptibility. Although ...
