The definition of the word: "make (someone) feel annoyed, frustrated, or worried, especially with trivial matters"
Still not seeing the magical connotation; seems pretty well grounded in human behavior, which is topical for Scientific American.
Wait.... what? Are you talking about Harry Potter?
It's hard to tell if you started as serious but are now becoming a parody troll account.
If you look up a linguistics corpus like the Corpus of Contemporary American English [2] or the British National Corpus [3] -- visit those sites, search for "vexing", and click on "VEXING" again -- you'll see a representative set of usages of the word "in the wild", and none of them appear to have anything to do with magic. There's also something in C++ called the "most vexing parse" [4], which too doesn't seem to have anything to do with magic. (By the way, you may like to try this exercise with "ritual" too, to see how the word is used in practice.)

It is deep in the literature that vexation is a domain of devils.
Begone, you.
