Also open the data manager and plot the data file "Sensor_1_Z_HTotal.DAT". This plot shows the variation of the magnetic field at the center of the magnets along the Z-axis. At z = 25mm, the magnetic field intensity is 260A275A/m.

== Simulating Permeable Magnets ==
In the previous parts, you assumed that the relative permeability of the permanent magnets was μ<sub>r</sub> = 1. Alnico is a permanent magnet material with μ<sub>r</sub> = 3.6. Open the property dialog of the group groups "PM_1" and "PM_2" in the navigation tree and change its relative permittivity to 3.6.
