What's the alternative to not explaining here? Is it making the magic subtle/weak/uncommon enough that the answer is "you didn't notice, and this is plausible to claim"? If the magic is blatant enough and there's no explanation, the story becomes even less attached to reality than "there's a lot of magic but it's deliberately kept hidden".
