    GRAVITY ANOMALY SEPARATION USING 2-D .

    Correct estimation and removal of the regional field from initial field observations yields the residual field produced by the target sources. Interpretation and numerical modelling are carried out on the residual field data, and the reliability of the interpretation depends to a great extent upon the success of the regional-residual separation. In literature some classical methods are ...

    Chapter 8 Introduction to Magnetic Fields

    Consider a long straight wire suspended in the region between the two magnetic poles. The magnetic field points out the page and is represented with dots (•). It can be readily demonstrated that when a downward current passes through, the wire is deflected to the left. However, when the current is upward, the deflection is rightward, as shown in Figure 8.3.1. Figure 8.3.1 Deflection of ...

    magnetic field will then be increased by a large factor which is usually expressed as a relative permeability for the material. w.wang 53 Long Range Order in Ferromagnets The long range order which creates magnetic domains in ferromagnetic materials arises from a quantum mechanical interaction at the atomic level. This interaction is remarkable in that it locks the magnetic moments of ...

    Magnetic Separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those who are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are less ...

    In particular, suppose a particle travels from a region of strong magnetic field to a region of weaker field, then back to a region of stronger field. The particle may reflect back before entering the stronger magnetic field region. This is similar to a wave on a string traveling from a very light, thin string to a hard wall and reflecting backward. If the reflection happens at both ends, the ...
