The Apple iPhone/MATLAB Mobile/LEGO MINDSTORMS Scanner, Part 2

This exercise is intended to help students to understand how to scan the magnetic anomaly of three disk-shaped Y10 magnets underneath a table. The experiment simulates a magnetic survey for subsurface structures.

The anomaly is mapped using the Apple iPhone/MATLAB Mobile/LEGO MINDSTORMS Scanner introduced in an earlier post. The quality of the result, possible artefacts, disturbances and other sources of error are discussed.
