    First of all, yes - Electromagnetics is a branch of physics. James Maxwell was a physicist.

    Second - Electromagnetics is not electronics. Electronics is a field that applies electricity and magnetism to make useful things.

      Yeah but Electromagnetics is the DEEP magic behind electronics.

      You could, if you wanted, use quantum mechanics and electromagnetic field theory to do circuit design. But unless you’re building quantum computers or doing simple circuit analysis and wanted a real challenge applying Kirchhoff’s Laws, there’s no need.

      So you can use the simplified electronics model where the current (and therefore primary charge carriers) is positive.

      No, That’s electrical engineering.

      Electronics is specifically the study and application of devices whose properties are determined by the charge carriers themselves (the electrons), ie. band gap semiconductors.

      Whether it’s science (physics) or engineering (EE) depends on why you are doing whatever you are doing. Understand stuff? Science. Make stuff that does stuff? Engineering.

      Of course, there’s a lot of bleed and cross pollination on the bleeding edge. This is known as the science/technology feedback loop.

        Dude, I’m sitting right now in front of a building full of people that basically study PN junctions for a living. If I tell them diodes are not physics they will be very upset.

          Sorry to upset the analogue stereo repair shop but you’re not exactly Stephen Hawkings, okay?

            Right now I’m standing in front of the building, so I’m definitely not Stephen Hawkings. Also I’m not dead.

            Also also, Hawkings was talented, but not a solid state physicist.

            If you want to troll here, you need to up your physics game. At least pick a relevant dude from the scores of Nobel prize winners my discipline has brought forth in the last fifty years or so.

            YOU ARE NOT RANDOM TV SCIENCE GUY I’VE HEARD OF doesn’t work here.
