Magic

Magic was a catchall term referring to any of a number of supernatural techniques outside of conventional Force powers.

The exact nature of magic remains in dispute among philosophers, as does its relationship to the Force proper. It is possible that all "magic" traditions were simply different methods of accessing the same Force, or were emanations of different aspects of it.

More so than the Force, magic potency could be trapped in artifacts or locations--but again, this may be just due to different methods of accessing and using the Force.

The term was also sometimes mistakenly used by primitives or less-informed people to refer to the Force powers of mainstream Jedi and Sith, who were likely to be called "wizards" and their abilities attributed to "magic".

Behind the scenes
Fans generally attribute textual references to "magic" (and for that matter, supernatural phenomena attributed to religions) as simply different interpretations of the Force.
