At room temperature, a sample of pure magnesium metal combines with oxygen to form a thin skin of magnesium oxide. At higher temperatures, it burns with a blinding white light, and because of this property it's used in fireworks. Read more at the link:

2Mg + O2 -> 2MgO (Magnesium Oxide)
But we all know that air is made not only of O2, but N2 too. The O2 is responsible for combustion; the N2, however, is unreactive at normal temperatures.
When we burn Mg in the air, the result will be 2 products: magnesium oxide (MgO) and magnesium nitride (Mg3N2).

The equation of a reaction of oxygen and magnesium to form magnesium is as follows:
2Mg (aq)+O2 (aq)-->2 MgO (s)
When it burns in oxygen, it would produce a strong white flame and its intensity may cause your eyes to go blind if you stare too close at it. It would react to form a compound called magnesium oxide which has a wood-ash appearance.
