Since you have AC current and therefore changing magnetic field, wouldn't disregarding electric fields, generally speaking, lead to incorrect results regarding the voltage? | |

It's a simple solver that works only on the magnetic fields not the electric fields. I think the likely answer is that irrespective of zero magnetic field lines close to the inner, there are field lines that suround it at distances outside the outer shield hence, induction does take place based on the rate of change of the total flux to infinity. Shorting the inner means applying a 0 volt source across its ends just like I applied a current source across the ends of the outer. | |
