Note: 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. [1913 Webster]
