Well Wolverine is one of my favorites other than magneto, but magneto would absolutely win because wolverine's skeleton has adamantium grafted to it. So unless it's not magnetic, magneto could rip him to shreds. Even if it's not magnetic, magneto could still just use any metal in the environment to do the same thing. Magneto is probably one of the most powerful mutants to ever live. Wolverine's very powerful and unique too, but he's just not in Magneto's league.
