I think we are saying the same thing. I used AC as in alternating current to specify that it must be time changing in comparison to steady flowing DC current. The requirement is that the source current must be changing in time to induce a voltage in nearby conductors. I believe that magnetic field coupling is the only method that is referred to as induction heating. It is possible to induce capacitive currents in nearby conductors as well but I do not think that process would be referred to as induction heating.

The current does not have to be alternating as in "reversing" directions periodically. All that is require is a time varying current, which could be Direct current, as long as it is varyinng. The important thing is the "varying" part and that should be enough to induce magnetic coupling on the metal substrate and induce Inductive Heating. Am I not correct? Jojo
