Is the tangential boundary condition of the magnetic field in the Eddy Currents Example continuous?

Hello everybody. I have some trouble in examing the Comsol Example in the following model AC/DC_Module/Tutorial_Models/coil_eddy_currents.

(1) I think the inner edge magnetic field boundary condition of R1 region(Cylinder) should not be continuous because of the surface induced current.
H1t - H2t = J_phi. In my point of view, the eddy current density J_phi != 0, whereas the tutorial has treated the inner boundary as continuality.

(2) How can I use the Vloop term in practical use, when I connect a solenoid of 500 turns to a 9V voltage suply?

Thanks a lot!
