Yes, this is exactly what I meant.
I told my Players that their help was needed for testing some new "magical technology", and that terminology just felt wrong. Sort of a contradiction of terms.
In that case, yeah, I'd go with Arcana.
Or, if we want to integrate 'em with above:
Thaumaturgy: the body of material pertaining to magic.
Thaumatology: the study of the theory and science that defines the principles of magic.
Thaumatological: pertaining to academic thaumaturgy; a
thaumatological formula.
Thaumaturge/Thaumatologist: one who is primarily concerned with the academic study of magic; a sage.
Arcana: the practical aplication of thaumaturgy; a spellbook is a book of
arcana, a magic sword is a work of
arcana.
Arcane: pertaining to the practical aplication of thaumaturgy; a spellbook is an
arcane tome, a summoning circle is an
arcane diagram.
Arcanist: one who primarily implements arcana; a wizard, sorcerer, artificer, etc.
Just off the top of my head.
