A Topographical Mapping of the Magnetic Field

I have conducted some measurements with my Gaussmeter (with a hall probe Siemens SAS 231W) on the X, Y and Z axis on a surface of 300x300mm, at 65 mm above a cylinder magnet (NIB) ( 22mm diam and 100 mm length). You will find below some topographical maps of my measurements (225 points for each surface plot).

As you can see on this topographical map of the Y-Axis (above), there is a DOUBLE VORTEX SETS at each pole of a magnet....
