Simulating a coil with current above ground, no B field found

I am building a simple AC/DC model: a half space as air, a half space as ground and there's a two-turn coil in the air above the ground. I want to put a AC current into the coil and get the magnetic field. I build a helix as the coil and set a current in the global definitions. I used magnetic fields as physics and added a multi-coil domain. However, there is no magnetic field after meshing and computing.
I'm quite new to comsol and wondering if you know which part is wrong in this model? I'll be really appreciated if you could give me a hand.
The model is attached below.
Best regards,
Yu
