Visuals of Magnetic Fields around a cylindrical rod (A Beginner's Question)

This is quite a simple projec I know, and I apologize in advanced for taking away any space that might have been used for a more pressing question.

To be quick, I'm working with a professor and he's set the task of me learning to use ComSol comfortably. I'm doing a few simple problems I know the answer to, to verify and get more accustomed to the program. My first is to model the magnetic fields around a cylindrical rod (3D) while a current is being passed through it. The answer, quite simple, is just concentric circles around the wire, however; it's getting to that end result thats proved difficult.

I'm familiar with geometry creation and material selection, the part that's gotten me is which physics I should be using or adding into the study to get the result I want. I'm not sure whether to use

Magnetic and Electric Fields
Magnetic Field Formulation
or Magnetic Fields
And what constraints or factors to add from that physics

If anybody could shine some light on the issue; maybe offer some advice, that would mean a great deal and would help incredibly.
Apologies again for such a meager question/issue.
