Magnet Release hasn't been explicitly stated to be Wind+Earth, but for the 2 characters that we have all the elements for (Gaara and Rasa), those are the only 2 they have in common

If a character was combining 3 natures, it wouldnt be Magnet Release anymore. From my understanding, Kajura uses lightning release alongside Magnet release rather than combining lightning, wind, and earth

It doesnt matter what materials Magnet Release is being used on, it doesnt change the basic mechanics of Magnet Release: manipulating magnetic fields

Long story short, Magnet Release being a combination of Wind and Earth doesnt make a whole lot of sense considering what it actually does, but it is what Kishimoto gave us. Boil Release can create acid and Lava release can be used to create rubber soooo yea....

EDIT:first paragraph, changed who had what elements
