Please!! Help!! Magnetic force between two magnet rings

I am trying to build a structure including two magnet rings on both ends and a central moving magnet cylinder. I want to see the change of the magnetic force on the central magnet with respect to the displacement when the central moving magnet is moving up and down. I have successfully modelled it using 2D axis symmetry and now I would like to simulate it using 3D model, but I cannot get the same results. I guess it is because the meshing way is not right. Is it possible to make the mesh more symmetric? In addition, I set the air sphere to be 'Magnetic Insulation', is it right ? maybe I should set the boundary of the air sphere to be 'Zero Magnetic scalar potential' ? Thank you so much. Attached is my model.
