Residual image

The output of the MagFit element in the network is the residual image. It can be visualized by adding a 2DPlot after the MagFit element.  

The residual image shows all deviations from the fitted theoretical magnetic field distribution used in MagFit.

On the left is the measured magnetic field distribution. On the right is the same distribution zoomed around the pole value.

In the residual image, shown below, material defects and magnetization inhomogeneities are readily visible.
