Magnetic field inside/outside of a conductive sphere

I want to determine the magnetic field inside and outside of a conducting sphere caused by point current sources inside the conductive sphere. I have 2 problems:

1) I am trying to use the current density calculated by the EC module in order to derive the Magnetic field but cant seem to couple the information from the EC module to the Magnetic Field module. I calculate the current density fine, but when I try to pull up an image of the Magnetic field I get no values.

2)I want to determine the field on the outside of the conductive sphere so I inclosed my conductive sphere in a larger sphere. I want to determing the field in the domain between the boundaries of the spheres. I keep getting an error every time I try to solve when I try to enclose my conductive sphere with the large one. Without the large sphere I get no errors and my solution converges.

Any help/advice on this would be GREATLY appreciated. I have attatched a copy of my model so far.

Thanks
JL
