Figure 9:Magnetic flux density at 0.1Hz in the region of the pipe near the plane of the source for (a) the “infinite” pipe, where the source is located at -4.5m and the pipe extends from 0m to -9m, (b) a “semi-infinite” pipe, where the source is located at 0m and the pipe extends to -9m. In (c), we zoom in to the top 5cm of the “semi-infinite” pipe, and (d) shows the 5cm at the top-end of the “infinite” pipe.
