When studying electronics I fell down the rabbit hole. Electricity and magnetism are inseparable. I knew of EMF but why did magnetism push something, where did the magnetism come from, what are domains, how is magnetism emitted from domains, how are the atoms involved, what are virtual particles...and so on.
When really as an electronics technican all I needed to know was magnets can move things.
