Electronics is a field that applies electricity and magnetism to make useful things.
No, That’s electrical engineering.
Electronics is specifically about devices whose properties are determined by the charge carriers themselves (the electrons or the electron holes), ie. band gap semiconductors.

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.
