Hi, i'm looking at the electromagnetic equation on the induction heating domain and I'm wondering about the terms multiplied by the potential vector. From which equations do they come?
I attached a photo that shows the terms I'm referring to.

Hi

you can derive this from Maxwell-equations in potential formulation plus Ohm's law
for time-harmonic fields:

in brief:

j = sigma*E = -sigma * dA/dt = i*omega*sigma*A

The second term is from the displaceemnt current and for electromagnetic waves
that should not influence induction heating.
