Magnesium itself is held together by metallic bonds, which are neither ionic nor covalent. Its compounds would tend to have ionic bonds.

Magnesium chloride has an ionic bond.
Magnesium chloride is a compound, not a bond of any kind. The compound is ionic.
MgO is magnesium oxide so it is an ionic bond.
If it bonds with another nonmetal, it will create a covalent bond. If it bonds with a metal, it will create an ionic bond.
In this case, Mg has a value of 1.3 and N has a value of 3.0, so it is an ionic bond. Ionic and covalent bonds are on a continuum. Some "ionic" compounds are in fact partly covalent because the positive cation (e.g. magnesium) polarizes (attracts the electrons of) the anion forming a stronger bond than if it was 100% ionic. A table of ELECTRONEGATIVITY can help one determine whether a bond is ionic or covalent. The bigger the difference in electronegativity the more ionic the bond.
Magnesium oxide has ionic bonds between magnesium and oxide ions.
MgCl2 features ionic bonds between the magnesium cations and the chloride anions.
It is covalent bond but with some ionic characters.
