Although with certain words magic is used more than magical, — as, magic circle, magic square, magic wand, — we may in general say magic or magical; as, a magic or magical effect; a magic or magical influence, etc. But when the adjective is predicative, magical, and not magic, is used; as, the effect was magical.
