UXO casings are extremely permeable in comparison to the host medium. Susceptibility is a measure of the extent to which a substance becomes magnetized when it is placed in an external magnetic field. 1 Moreover, in the case of AF, it is the susceptibility of one sub-lattice (that with the magnetic moment parallel to the applied field), and only at the zero point of magnetic curve, i.e. Identify the following magnetic materials: (i) ... Susceptibility of a magnetic substance is found to depend on temperature and the strength of the magnetising field.

The permeability μ is often used for ferromagnetic materials such as iron that have a large magnetic susceptibility dependent on the field and the previous magnetic state of the sample; permeability is defined by the equation B = μ H. From equations (8) and (9… Example – 07: Magnetic field and magnetic intensity are respectively 1.3 T and 900 A/m. Ans: Relative permeability is 1273 and susceptibility is 1272. Magnetic Permeability. Magnetic susceptibility, k, is related to magnetic permeability (m) by: Calculate permeability and magnetic susceptibility of the rod. 5.7k SHARES. The magnetic susceptibility is a dimensionless proportionality constant that indicates the degree of magnetization of a material in response to an applied magnetic field. Magnetic Susceptibility The magnetic susceptibility of a magnetic substance is defined as the ratio of the intensity of magnetisation to magnetic intensity $\chi_{ m }=\frac{ I }{ H }$ It is ratio of two quantities with same units $\left( Am ^{-1}\right)$ so has no units. MEDIUM. Magnetic Dipole Moment 1. Given: Magnetic field = B = 1.3 T, magnetic intensity = … −µr > 1 implies material magnetizes in response to the applied magnetic field. Equation (1) may be written as , where . Magnetic Permeability. A magnetic material placed in a magnetising field of magnetising intensity H, the material gets magnetised. The slope of the former when divided by the magnetic space constant, μ 0 gives the magnetic susceptibility and the slope of the latter gives the magnetic permeability, μ (= μ 0 μ r). 4 π × 10 −7 N⋅A −2 is the magnetic permeability of free space. A good magnetic core material must have high permeability. The magnetic susceptibility is a dimensionless proportionality constant that indicates the degree of magnetization of a material in response to an applied magnetic field.
