Where I first encountered this topic was in an old romanian textbook that I have called "Physics". The topic is part of a chapter called "Types of electric currents"
Here is section where they briefly touch on convection current
So, I randomly came upon this in a textbook that I was skimming and I think I have a very very surface ideea of what it's about but I want to read and know more in order to understand the fenomenon in much more detail. Any help in any form would be much appreciated!
P.S.: This is my first post...
