Particles that follow a surface

HI I’m new to the forum and I’m trying to learn Notch, I would like to know how particles can perfectly follow a surface in this case in my example a sphere (the sphere is in mode 0 so invisible), I put a Mesh Attractor but it does not fill the goal, I would like to see your opinions, thank you.

attached the examples that I made in image

Hi all, I found the solution, it was necessary to explore, to play with the options of the Mesh Attractor.
Here’s the result!
