Hello all, I've been examining plasma physics and electricity (or at least trying to with a search engine) and have a few questions. 1. Can plasma be polarized? For example, if a magnet is placed with the "north" polarity near a magnet, will it maintain that shape? 2. If a wire carrying an electric current is heated, will it produce a higher current (more electricity)? 3. What happens to free electrons when they are confined in between two magnets of differing polarities? Same polarities? These are not homework questions, just questions of my own i'd like answered.
