The rapid progress in the expanse of electromagnetic devices among the broad scale of industrial, military, commercial and consumer sector has led to a surge in electromagnetic interference which has now become the fourth most prevalent category of pollution. Thus, there is a dire need of developing materials which can shield the devices of its adverse effects. This review sets foot into what so far has been done in order to develop such shielding materials by targeting Mg. The dependence in shielding effectiveness on variation in heat treatment, concentrations of the alloying elements, forming processes and its combinations have been addressed in this review.
