Force Field effect tutorial

Hello all, I’ve been looking for a tutorial to create a “force field” effect, basicly I have a box sphere and I want to add an effect on it’s bounds so it’s more clear where the boundaries are, but I can’t find any tutorials!
What I am looking for is something like this:

Does anyone know where I can find a tutorial to do something like this?

instead of adding a material to the collider, just add an actual transparent/forcefield material to your sphere and have colliders enabled.
