The field probes are used to investigate the magnetic field profile. Probes are made in the same way as conductors, by choosing the appropriate type from the Config menu. Field probes have associated with them a window which displays the calculated field graphically. The name of the window is the name of the probe object preceded by the symbol Pi, meaning product. This section describes the field probe parameters, which control both the placement of calculated points and the plotting of the results.
There are two kinds of probes:
