You need to use the “Surface Streamlines” feature of the stream tracer.  
Here is how to do it.

- Open ParaView
- Open your vector field, apply
- Create a Sphere source, set the radius to a specific value, set the resolution to a high enough value (80, 80 should be ok), Apply
- Click on your vector field in the pipeline browser
- Add a resample with dataset filter, select your sphere as a source, Apply
- Create a sphere source, set the radius to the same value as the other sphere, set the resolution to have enough seed for your streamlines (20, 20 should be ok), Apply
- Click on the resample with dataset, in the pipeline browser
- Add a StreamTracer with custom source, select the second sphere as a source, Apply
