Plotting magnetic field w.r.t distance along z-axis

Hi all,

I've adopted the following model:

www.comsol.com/model/static-fi...eling-of-a-halbach-rotor-14369

I've changed the magnetic field to be confined within the rotor through simply changing the directions of the individual magnets.

I'm new to COMSOL, and wanted to know is it possible to plot the magnetic field strength within the inner circle of the halbach rotor along the z-direction distance?

I wanted to start at the center of the rotor (0,0) and go both directions, say 40mm to the right and 40mm to the left: 40mm and -40mm and show the field strength along the z-direction.

Is it a good idea to plot the flux density normal (T) or the magnetization along X and Y vs. Z distance?

Kind Regards,
Dan
