The discussion centers on several complex questions regarding electromagnetics, particularly the application of Kirchhoff's Voltage Law (KVL) in AC circuits, the distinction between conduction and convection current densities, and the boundary conditions for time-varying fields. It is noted that KVL appears violated in AC circuits due to time-varying magnetic fields, but this is reconciled by considering parasitic inductance in the circuit. The differences between conduction current (movement of electrons in a conductor) and convection current (movement of charged particles in a vacuum) are clarified, emphasizing their distinct mechanisms. Additionally, the boundary conditions for electric and magnetic fields are debated, particularly regarding the treatment of surface charge and current densities. The conversation reflects the ongoing challenges and misconceptions in understanding electromagnetic principles.

Also I'll point out that you have completely hijacked this thread so it is focused on a topic taken from your own, different thread.

You read the original question? Question 1 is on KVL under magnetic field condition. Question 3 about tangential boundary condition which talk about free charge and free current. Where is it off the topics when I talk about MIT professor Levine. He made a video demonstrated KVL don't hold under varying magnetic field. AND current in transmission line are consequence of EXACTLY the tangential boundary condition between good conductor and dielectric. You watch the video I posted before you speak?

This thread will remain closed. I've asked yungman to take the debate to PMs if he wants to continue it.
