Overview
Figure B-2 The Earth's magnetic field interacting with a magnetizable body.
Anomalies
An anomaly is created when the Earth’s magnetic field is disturbed by an object
that can be magnetized. The resultant anomaly can also be viewed in terms of
vectors as previously described for (Figure B-2). When this is measured and
plotted against the measuring location, you may see a profile of values as
illustrated in (Figure B-2), showing a local disturbance of 10 nT. It is very
important to note that the vector of the local disturbance can be in any direction.
This is always the case with buried drums, as we shall see in Chapter 3.
