Problem to setup an simulation case

Hi there, I'm new to use this simulation software. I tried to simulate a rotating magnet which create another maganetic field among the balls in a bearing. Those bearing balls rotate themself and revolute the shaft in a parallel plan with the magnet. The round diametrical magnetized magnet has its own magnetic field, as a vector A. Those bearing balls would be generated a combined magnetic field by the rotaing magnet, as a vector B. In our experiment, the vector A shows a little diffefence direction from vector B.

I tried to simualte this situation followed the tutorial "Application ID: 10437 Rotating Machinery 3D Tutorial". In the beginning model, I left out the bearing balls' self-rotion and only simulate the revolution of the bearing balls via a rotating magnet. But the result is not as my expectation.

The magnet looks like having a rotation but the stream line of magnetic flux density hasn't. And the stream lines don't show up in the lower cylinder part.

Can any one give me the suggetion of the configuration of this case? Thanks a lot!!
