Quantitative analysis of the relationship between non ...

The quantitative relationship between non-uniform stresses and stress-induced residual magnetizations in ferromagnetic materials under geomagnetic fields was investigated. A ferromagnetic steel specimen with two symmetric notches was stretched to generate a non-uniform stress distribution. The residual leakage magnetic field and surface strain of the specimen were detected.

While the charged particle travels in a helical path, it may enter a region where the magnetic field is not uniform. 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.

Contrary to the regional fields obtained by upward continuation, non-linear filtering does not have any physical meaning. However, its main advantage is that it gives a regional component of the gravity or magnetic field similar to the one obtained from a graphical separation.

The magnetic field produced by the regional susceptibility model is then used as the regional field, and the residual data are obtained by simple subtraction. The advantages of this method of separation are that it introduces little distortion to the shape of the extracted anomaly and that it is not affected significantly by factors such as ...

Typical values for ordinary liquids and solids are in the range µr = 1.00001 to 1.003. −µr = 1 when the material does not respond to the magnetic field by magnetizing. −µr > 1 implies material magnetizes in response to the applied magnetic field.

Separation of regional and residual magnetic field data

the stripping method is a more suitable approach for residual separation. However, the lack of reliable information about the magnetic sources to be removed prohibits its use in most practical cases. The above methods for regional-residual separation have been successfully incorporated into the processing and inter-pretation of magnetic data.
