No. It is reduced.

Explanation:

The oxidation numbers for the ions in $"FeCl"_2"$ are $+2$ and $-2$ , respecitively. The product $"Fe"$ is in its elemental state, and therefore has an oxidation state of $0$ . So the oxidation number for $"Fe"^(+2)"$ is reduced from $+2$ to $0$ in the product $"Fe"$ . A reduction reaction involves the gain of electrons.

$"Fe"^(+2) + 2e^-$ $rarr$ $"Fe"$

The oxidation reaction is the change of elemental $"Mg"$ from $0$ to $"Mg"^(+2)$ . The oxidation reaction involved the loss of $2$ electrons from elemental $"Mg"$ .

$"Mg"$ $rarr$ $"Mg"^(+2) + 2e^-"$
