All magical items are considered magical weapons or armor. Ice weapons of Caelum are considered magical. Mind Blasts of R'lyeh are magical. few special units wield magical weapons: Eternal Knights of the merc company wield Flambeau, some heroes wield magical armor identical to what they would get from wielding a magical suit of armor (a C'tissian hero has Rainbow Armor?), etc.

At least magical weapons are shown to be magical when you right-click on them on unit properties. I don't think I've ever seen an armor stated as magical, and I'm not sure if the modding commands allow for making an armor magical.
