Aqueous solution of NaOH or something else?

 

not at all, especially in aqueous solution.

look up reactivity series.

 

I dont think sodium can be distilled out of the mix of molten NaOH and Mg too easily or you could cheat with Le Chatlier's principle and a lot of heat.

Agreed, all it does, is induce the corrosion of the magnesium metal, and release hydrogen gas, in the process.

 

Actually, I think the corrosion of the magnesium would be hindered by formation of a hydroxide skin. Unlike aluminum hydroxide/oxide, which you are probably thinking of, magnesium hydroxide is not amphoteric.
