Probes

---

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.

There are three kinds of probes:

• Tracer probe
• Linear probe
• Planar probe

Linear and Planar 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 in square brackets.

The probes may display a number of pre-defined quantities, such as the magnetic induction B or the magnetic vector potential A. In addition, a macro language function can be specified on the Macro tab of the probe edit dialog. To plot the result of the evaluation of the macro, select the macro result (f) on the Plot tab.
