Air is a mixture containing mainly nitrogen and oxygen.

When magnesium burns in air, it reacts with both oxygen and nitrogen to form magnesium oxide and magnesium nitride, respectively.

The chemical reactions are:
$2\mathrm{Mg}+{\mathrm{O}}_2\to 2\mathrm{MgO}$
$3\mathrm{Mg}+{\mathrm{N}}_2\to {\mathrm{Mg}}_3{\mathrm{N}}_2$

Therefore, the products formed are $\mathrm{MgO}$ and ${\mathrm{Mg}}_3{\mathrm{N}}_2$.

Answer: MgO and ${\mathrm{Mg}}_3{\mathrm{N}}_2$
