of the applied stress relative to the magnetic field. When the applied stress is parallel to the magnetic field the susceptibil- ity decreases; when the stress and field are perpendicular, there is an increase in magnetic susceptibility [e.g., 82]. The amount of change is reversible, and is dependent both on composition and on magnetic grain size.

Magnetic separation is a process used to separate materials from those that are less or non­magnetic. All materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. The few materials that are strongly affected (magnetised) by magnetic fields are known as "Ferromagnetics", those lesser (though noticeably) affected are known as ...

Introduction Magnetic fields. Magnetic fields are vector quantities characterized by both strength and direction. The strength of a magnetic field is measured in units of tesla in the SI units, and in gauss in the cgs system of units. 10,000 gauss are equal to one tesla. Measurements of the Earth's magnetic field are often quoted in units of nanotesla (nT), also called a gamma.

Rock magnetism is the study of the magnetic properties of rocks, sediments and soils.The field arose out of the need in paleomagnetism to understand how rocks record the Earth's magnetic field. This remanence is carried by minerals, particularly certain strongly magnetic minerals like magnetite (the main source of magnetism in lodestone).An understanding of remanence helps paleomagnetists to ...

Magnetic Materials

Diamagnetic materials have a weak, negative susceptibility to magnetic fields. Diamagnetic materials are slightly repelled by a magnetic field and the material does not retain the magnetic properties when the external field is removed. In diamagnetic materials all the electron are paired so there is no permanent net magnetic moment per atom.
