No. It is reduced.

Explanation:

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

${Fe}^{+ 2} + 2 e^{-}$ $"Fe"^(+2) + 2e^-$ $\to$ $rarr$ $Fe$ $"Fe"$

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

$Mg$ $"Mg"$ $\to$ $rarr$ ${Mg}^{+ 2} + 2 e^{-}$ $"Mg"^(+2) + 2e^-"$
