Fortunately only a few minerals occur abundantly enough in nature to make a significant contribution to the induced and remanent fields. w.wang 46 Magnetic susceptibility and permeability In large class of materials, there exists a linear relation between M (internal magnetization) and H (external applied magnetic field)M = χH χ is positive then the material is called paramagnetic χis negative then the material is diamagnetic A linear relationship also occurs between B (magnetic flux density) The force is measured with the magnetic field turned ON and with the field OFF at a given temperature (e.g., room temperature). 1a. Magnetic materials 1) Magnetic Induction or Magnetic Flux density (B): The magnetic induction or magnetic flux density is the number of lines of magnetic force passing through unit area perpendicularly. Where Φ is the magnetic flux and A is the area of cross section. Typically, the sample tube is calibrated with a known standard. Magnetic Susceptibility. Magnetization (M) and Magnetic field (H) are related by a term known as Magnetic Susceptibility (.) Magnetic susceptibility is defined as the degree of magnetization of material when placed in a magnetic field. (2) The magnetization can be defined as E M B ∂ =− ∂, (3) where E is the total energy of the system. 20 25 30. The magnetic susceptibility factor χ arises from the magnetization M induced in a material exposed to an external magnetic field H 0, corresponding to a magnetic induction B 0 =μ 0 H 0, in the absence of the material, where μ 0 =4π×10 −7 (T m A −1) is the magnetic permeability in vacuum. Measure- Curie law of the magnetic susceptibility 0 100. the magnetic susceptibility, spatial distribution and concentration of the local crustal materials. 4/30/2015 J.Subrahmanyam Confidential 1 2. magnetic field gradient, which is not very practical! 600. define the magnetic susceptibility as follows M B χ ∂ = ∂. 35. 0 5 10. 11 The out-of-phase component of the susceptibility is nonzero for temperatures slightly below the transition temperature, where magnetic irreversibility occurs in the sample. magnetic susceptibility of a number of materials by using a sample, a magnetic field, and a mass balance, and compare the values to the known material susceptibilities. as: M = .H. example of AC susceptibility of the high-temperature super-conductor LaBaCa(Cu 1-xZn x)O 7- δ. is shown in Fig. 3. In other words, it is the magnetic field which material itself produces. Magnetic materials 1. 300 400 500. THEORY: For diamagnetic materials, let us imagine that an atom that is a nucleus in a stationary cloud of electrons is placed in a magnetic field, as in Fig. 200. Definitions (2) and (3) are more general and can be used in calculations. Magnetic Field: The magnetic field is an imaginary line of force around a magnet which enables other ferromagnetic materials to get repelled or attracted towar… O SlideShare utiliza cookies para otimizar a funcionalidade e o desempenho do site, assim como para apresentar publicidade mais relevante aos nossos usuários. 15. mol −1 (CGS) and is defined as $\chi _{\text{mol}}=M\chi _{v}/\rho$ 40 45 50.
